The open/select of the PLM is done in orte/mca/ess/base/ess_base_std_orted.c. It only is done when the PLM MCA param is set directing a specific PLM be selected. The function
orte_plm_base_orted_append_basic_args
clears the params passed to the daemon of any PLM selection passed to the HNP. Each PLM then adds a PLM directive if-and-only-if backend PLM support is desired. At present, Torque, SLURM, and rsh all specify this support and direct that the backend orted open the "rsh" PLM.

If we do not initialize the PML, non-HNP daemons will not be able to use its functions. For example, RSH needs it when the tree_spawn mode is
enabled: daemons call orte_pml.remote_spawn() function to spawn their children in the deployment tree.

Update the loop_spawn test to remove a sleep so that it runs at max speed, letting the new code catch when we overrun ourselves and wait for room to be cleared for the next comm_spawn.

Shiqing -- is there a missing file in this directory? If so, please
add it and restore the EXTRA_DIST line I just removed. Thanks!

way to have no abort message is to pass NULL (the errmanager is smart
enough to handle this case and not emit any extra message).
This commit was SVN r21311.
Emit a more informative error message when the file descriptor limit is
reached during an accept() call. Also, abort when the accept fails to
avoid an infinite loop.
Emit a more informative error message when the help file can't be opened.

Add a new tm ess module that exploits this capability.
Update the various plm modules to enable it - just a minor change reflecting an added param to a plm base function.
Additional fixes included:
1. remove an erroneous cleanup of session directories in the tool finalize procedure - tools don't create session directories to begin with!
2. fix a duplicate free when attempting to execute a non-existent app
3. cleanup an typo in the comm utilities
4. fix comm_spawn - was perturbed by the changes in pack/unpack of orte_job_t to properly support orte-ps
Been tested on slurm and tm machines, using all tests in orte/test/mpi. May run into issue with command line length on large jobs due to inclusion of node info to support static ports - will fix this next with addition of regexp generator to compress that info.

1. replacing mpi_paffinity_alone with opal_paffinity_alone - for back-compatibility, I have aliased mpi_paffinity_alone to the new param name. This caus
es a mild abstraction break in the opal/mca/paffinity framework - per the devel discussion...live with it. :-) I also moved the ompi_xxx global variable
that tracked maffinity setup so it could be properly closed in MPI_Finalize to the opal/mca/maffinity framework to avoid an abstraction break.
2. Added code to the odls/default module to perform paffinity binding and maffinity init between process fork and exec. This has been tested on IU's odi
n cluster and works for both MPI and non-MPI apps.
3. Revise MPI_Init to detect if affinity has already been set, and to attempt to set it if not already done. I have *not* tested this as I haven't yet f
igured out a way to do so - I couldn't get slurm to perform cpu bindings, even though it supposedly does do so.
This has only been lightly tested and would definitely benefit from a wider range of evaluation...
