Haven't fully tested these yet (nobody is using them at the moment that I know of - good thing, since they haven't been working for a long time - though I know the MPI-2 stuff needs the functionality), but will do so shortly. For now, they compile.

1. Modify the registry to eliminate redundant data copying for startup messages.
2. Revise the subscription/trigger system to avoid redundant storage of triggers and subscriptions. This dramatically reduces the search time when a registry action occurs - to illustrate the point, there are now only a handful of triggers on the system for each job. Before, there were a handful of triggers for each PROCESS in the job, all of which had to be checked every time something happened on the registry. This is much, much faster now.
3. Update all subscriptions to the new format. There are now "named" subscriptions - this allows you to "name" a subscription that all the processes will be using. The first one to hit the registry actually defines the subscription. From then on, any subsequent "subscribes" to the same name just cause that process to "attach" to the existing subscription. This keeps the number of subscriptions being tracked by the registry to a minimum, while ensuring that each process still gets notified.
4. Do the same for triggers.
Also fixed a duplicate subscription problem that was causing people to receive data equal to the number of processes times the data they should have received from a trigger/subscription. Sorry about that... :-( ...but it's all better now!
Uncovered a situation where the modex data seems to be getting entered on the registry a second time - the latter time coming after the compound command has been "fired", thereby causing all the subscriptions to fire. Asked Tim and Jeff to look into this.
Second phase of the changes will involve modifying the xcast system so that the same message gets sent to all processes. This will further reduce the message traffic, and - once we have a true "broadcast" version of xcast - really speed things up and improve scalability.

1. Fix the reigstry's overwrite logic. It was only overwriting the first keyval specified in a value - the rest were just added on regardless of whether or not the keyval already existed. This was the source of the multiple keyvals some people were seeing - should be fixed now.
2. Change the orted command parsing options so it reports options that aren't recognized - should help reduce confusion

* Add ability to completely disable libltdl (the dlopen code to load
dynamic shared objects) to configure: --disable-dlopen
* Added MCA param (component_disable_dlopen) to disable DSO loading
at runtime
* Made the event library behave in some not-completely-erroneous way
on platforms where it has absolutely no eventops support (ie, no
select, poll, or epoll)
* Disabled orte_wait, opal_few, and opal_daemon_init code on
platforms without fork, waitpid support. All non-init functions
will return OPMI_ERR_NOT_SUPPORTED
* Disable orteprobe tool when fork or pipe aren't supported

- it will now wait for the child procs to exit then kill off the daemons
- if orted is in your path it will automatically be found, or you can
specify its location.
- your LD_LIBRARY_PATH is now forwarded to the backend to make it easier to use
shared libraries in nonstandard places
Still need to work on cleanup on the backend nodes.

sockaddr_in - seems to be a good indicator)
* disable util/if code if no inet devices (again, no sockaddr_in)
* add enable/disable flag to disable stacktrace pretty-print code
(defaults to enabled). Seems there's something funky going on with
the preprocessor on Red Storm that was causing problems - this was
the easiest fix
* clean up a bunch of the configure.m4 files to remove bogus comments,
properly comment them, fix the dumb logic for happy/unhappy
* Create a macro for testing both header and library for a package,
since we seem to do this kind of test quite often. Handles the
-I and -L search paths properly (including stripping out /usr and
/usr/local if not needed)
* Converted mvapi components to configure.m4, using the nice new
ompi_check_package macro (above)

threads (basically, same as before, but we now link the right thread
libraries).
* Add disable-io-romio flag to disable compiling ROMIO
* Migrathe mvapi btl from configure.stub to configure.m4

components to succeed with --enable-dist. Instead, just add them to
all_components and make dist will still work - we're going to stamp out
the Makefiles no matter what
* Add missing header to ob1 pml for make dist
* Clean up the Portals BTL configure code
