the way fboxes works has issues for the sessions implementation,
in particular tthe session finalize approach.

what happens without this temporary fix is that if there is not some fully shcnronizing call
prior to calling session_finalize, there are cases where a process may be probing its fast
mailboxes for processes that are tearing down theses fboxes.  That results in segfauls and
sigbus problems.

The fast box mechanism will need to be supplemented with some kind of shutdown mechanism
that will tell the owner of the fboxes when its okay to actually tear them down.

IN the interest of making progress using the sessions prototype with applications, shut
down the fbox process for the prototype and return to coming up with a real fix at a later
date.

drop use of MPI_Flag

what we're reading at the forum now for Sessions proposal has ditched MPI_Flags.
Now using info object to MPI_Session_init to specify thread support level
desired.

Turns out that the predefined datatypes are initialized statically,
so the first time through calling ompi_datatype_finalize the magic
cookie gets cleared if code is compiled in debug mode.  This results
in a second call to ompi_datatype_finalize to blow up with an assert
since the cookie had been cleared in the first pass.

Add a new OBJ_DESTRUCT variant which does not check/clear cookie even
when the code is compiled in --enable-debug mode.

The fix to not destruct the predefined datatypes seem to have

None of these made it into the sessions API for MPI 4.0 and its very
likely they will be added in a MPI 5.0 release.  Other approaches to topology
