following:
* Provides a fixed number of resource slots (i.e., "hotel rooms").
* Allows one thing to occupy a resource slot at a time (i.e., each
hotel room can have an occupant check in to that room).
* Resource slots can be vacated at any time (i.e., occupants can
voluntarily check out of their hotel room).
* Resource slots can be occupied for a specific maximum amount of
time. If that time expires, the occupant is forcibly evicted and
the upper layer is notified via (libevent) callback (i.e., the maid
will kick an occupant of out of their room when their reservation
is over).
This class can be to be used for things like retransmission schemes
for unreliable transports. For example, a message sent on an
unreliable transport can be checked in to a hotel room. If an ACK for
that message is received, the message can be checked out. But if the
ACK is never received, the message will eventually be evicted from its
room and the upper layer will be notified that the message failed to
check out in time (i.e., that an ACK for that message was not received
in time).
Code using this class is currently being developed off-trunk, but will
be coming to SVN soon.

- OMPI_SUCCESS
- OMPI_ERROR
- OMPI_ERR_RESOURCE_BUSY
If an "OMPI_ERR_OUT_OF_RESOURCE" occurs, the request is added to the pending list, and will be handled later. An error message
should not be printed to the user in this case. This is not an error, but rather a notification of a possible valid condition.
Only in the case of "OMPI_ERROR" should it be printed to the user.

btl_openib_connect_udcm when notifying not to listen to an fd to ensure
that the main thread does not continue until the service thread has
processed the message
Adds ability to send message to openib async thread to tell it to
ignore the ERR state on a specific QP. Adds this call to udcm_module_finalize
so when we set the error state on the QP it doesn't cause the
openib async thread to abort the mpi program prematurely
Fixes trac:3161

therefore break RoCE.

Still need clarification on the MPI_Init portion of the ticket. Specifically, does the ticket call for returning an error is someone calls MPI_Init more than once in a program? We set a flag to tell us that we have been initialized, but currently never check it.

aren't separated out into individual commits; they represent a few
months of work in the Mercurial branch, and it seemed error-prone to
try to break them up into multiple SVN commits.
* Remove 2nd overloaded interfaces for MPI_TESTALL, MPI_TESTSOME,
MPI_WAITALL, and MPI_WAITSOME in the "mpi" module implementations
(because we're not allowed to have them, anyway -- it causes
complications in the profiling interface). This forced an MPI-2.2
errata in the MPI Forum; we applied the errata here (the array of
statuses parameter could not have a specific dimension specified in
the dummy argument). Fixes trac:3166.
* Similarly, fix type for MPI_ARGVS_NULL in Fortran
* Add MPI_3.0 function MPI_F_SYNC_REG (Fortran interfaces only).
* Add MPI-3.0 MPI_MESSAGE_NO_PROC in the mpi_f08 module.
* Added mpi_f08 handle comparison operators, per MPI-3.0 addendum to
the F08 proposal at the last Forum meeting.
* Added missing type(MPI_File) and type(Message) in mpi_f08 module.
* Fix --disable-mpi-io configure switch with all Fortran interfaces
* Re-factor the Fortran header files to be fundamentally simpler and
easier to maintain. Fortran constant values in the header files
are now generated by a script named mpif-values.pl during
autogen.pl (they were previously generated by mpif-common.pl, but
it was quite a bit more subtle/complex). A second commit will
follow this one to update svn:ignore values (just to ensure we
don't muck up the first commit with the SVN client getting confused
by the changed ignore values and new/changed files).
* Fix some dependencies for compile ordering in
ompi/mpi/fortran/use-mpi-ignore-tkr/Makefile.am.
* Fix bad wording in several places (.m4 file name, ompi_info output,
etc.): we previoulsy said "F08 assumed shape" when we really meant
"F08 assumed rank" (for Fortran gurus, those are very different
things).
* Removed the GREEK/SVN version string from mpif.h. It really had no
purpose being there.
Still to be done:
* Handling of 2D array of strings in MPI_COMM_SPAWN_MULTIPLE still
isn't right yet. Not sure how many people really care about this
:-), but it is still broken.

accidentally adding component names to the OMPI_MPIEXT_ALL_SUBDIRS
variable twice; once with mpiext/ and once without. And then
prefixing all of them with mpiext/ again at the end. That wasn't
really necessary :-) -- we only need to add it once (without mpiext/)
and then prefix at the end (for consistency with the
OMPI_MPI_EXT_*_SUBDIRS handling).
