The problem was that we close the same fd twice, and that meantime the fd could have been reassigned
to some other file or socket.

1. remove direct routed module (hooray!)
2. add radix tree routed module (binomial remains default)
3. remove duplicate data storage - orteds were storing nidmap and pidmap data in odls, everyone else in ess
4. add ess APIs to update nidmap, add new pidmap - used only by orteds for MPI-2 support
5. modify code to eliminate multiple calls to orte_routed.update_route that recreated info already in ess pidmap. Add ess API to lookup that info instead. Modify routed modules to utilize that capability
6. setup new ability to shutdown orteds without sending back an "ack" message to mpirun - not utilized yet, will require some changes to plm terminate_orteds functions in managed environments (coming soon)
Initial tests indicating that fully routing comm via defined routing trees may not actually have a significant cost for operations like IB QP setup. More tests required to confirm.
This will require an autogen...

Without this patch, doing spawn in a loop ended up by exhausting all
available file descriptors pretty quickly. There were about 5 file
descriptors opened per spawned process. Now the number of file
descriptors managed by the process (orted or HNP)
is a lot smaller.

Modify read_write test to allow specification of rank to read stdin.
IOF now validated to work for arbitrary rank as stdin target. Not validate to work for multiple simultaneous ranks reading stdin (untested).

1. remove some stale files that were overlooked in original commit
2. add a test program and data to stress iof for stdin
3. cleanup a debug statement that caused memory corruption when reading large files
4. some minor cleanups to correctly handle xon/xoff scenarios
This commit was SVN r19792.
1. completely and cleanly separates responsibilities between the HNP, orted, and tool components.
2. removes all wireup messaging during launch and shutdown.
3. maintains flow control for stdin to avoid large-scale consumption of memory by orteds when large input files are forwarded. This is done using an xon/xoff protocol.
4. enables specification of stdin recipients on the mpirun cmd line. Allowed options include rank, "all", or "none". Default is rank 0.
5. creates a new MPI_Info key "ompi_stdin_target" that supports the above options for child jobs. Default is "none".
6. adds a new tool "orte-iof" that can connect to a running mpirun and display the output. Cmd line options allow selection of any combination of stdout, stderr, and stddiag. Default is stdout.
7. adds a new mpirun and orte-iof cmd line option "tag-output" that will tag each line of output with process name and stream ident. For example, "[1,0]<stdout>this is output"
This is not intended for the 1.3 release as it is a major change requiring considerable soak time.

There is still a problem with OpenIB and threads (external to C/R functionality). It has been reported in Ticket #1539
Additionally:
* Fix a file cleanup bug in CRS Base.
* Fix a possible deadlock in the TCP ft_event function
* Add a mca_base_param_deregister() function to MCA base
* Add whole process checkpoint timers
* Add support for BTL: OpenIB, MX, Shared Memory
* Add support Mpool: rdma, sm
* Sundry bounds checking an cleanup in some scattered functions

The segv was caused by the fact that we don't really know which daemon failed to start (at least, in most cases), so we didn't set a pointer to the aborted proc object. All we really wanted, though, was to ensure that mpirun returned a non-zero exit status, so the fix was to simply return the default error status.

- Unify the Windows and the others way of handling callbacks. Thanks to George.
- This will let Windows use the same callbacks as Linux does, which works also.

Refers to ticket #1548. Although this appears to fix the problem, the ticket will be held open pending further test prior to transition to the 1.3 branch.

thereby runs apstat twice; and in the process thereof reads the ALPS
appinfo file TWICE; and in addition, experiences a failure sometimes
which causes mpirun to hang. Change this to a looped read attempt
that breaks on success, thereby avoiding failure (except in the most

Add --display-devel-map and --display-devel-alloc to display all the detailed info we used to provide - it is only of use/interest to developers anyway and confuses users.

Cleanup when an orted actually opens the PLM. Unfortunately, some unmentionable people are pushing head node environs out to remote nodes, causing the daemons to think they are the HNP. This helps prevent the confusion.

The problem was that (outside of Odin configure issues) that the IOF is no longer enabled by application processes.
Checkpoint/restart seems to be working once again.
Thanks to Ralph for pointing me here.

* Protect an orte variable used in the orte debugger stuff
* Initialize the datatype code in the Catamount code, as we need it
for intercommunicators (the proc code needs it to pack the remote
name)
* Turn on a bunch of the orte datatype code so that ORTE_NAME is available.
