is something going on with the subscription not getting called. E-mail
coming to those interested.

* add MCA parameter (OMPI_MCA_mpi_yield_when_idle) to cause sched_yield()
to be called when the progress engine is called and nothing happens.
Default is to call sched_yield().
* add MCA parameter (OMPI_MCA_mpi_event_tick_rate) to adjust the rate
at which the event library is called from ompi_progress. When set
to 0, the event library will never be ticked. When set to 1, the
event library will be progressed every time. 2 every other, etc.
The MCA parameters are only in effect from end of MPI_Init to start of
MPI_Finalize.

the way progress is done in the non-threaded case, adds a progress
thread for the threaded progress case (which should be made to use
George's progress engine when it is ready), and fixes some bugs with
request handling, especially with freeing requests (IO requests, that
is).

support is included because ROMIO is inherently thread-unsafe.
One possible way to have true asynchronous progress would be to use a
progress thread that wakes up and polls at some frequency when there
are non-blocking IO requests pending. This is pretty icky, though --
it should definitely have an MCA parameter to enable/disable this
functionality, as well as another to control the polling frequency.
This also strengthens the argument that we need a v2 of the io
framework -- one that is not designed to exclusively support ROMIO --
one that does something unimaginably "better" for the parallel MPI-2
IO interface. :-)
