Ralph, did you get a chance to run the ibm/final test to see if these
changes fixed the problem? I just rebuilt the trunk and tried it and I
still get an exit status of 0 back. I will run it again to make sure I
have not made a mistake.

Okay, this should finally be fixed. See the commit message for r23045
for an explanation.
It really wasn't anything in the cited changeset that caused the
problem. The root cause is that $#@$ abort file we dropped in the
session dir to indicate you called MPI_Abort vs trying to thoroughly
cleanup. Been biting us in the butt for years - finally removed it.

The ibm/final test does not call MPI_Abort directly. It is calling
MPI_Barrier after MPI_Finalize is called, which is a no-no. This is
detected and eventually the library calls ompi_mpi_abort(). This is
very similar to MPI_Abort() which ultimately calls ompi_mpi_abort as
well. So, I guess I am saying for all intents and purposes, it calls
MPI_Abort.

I'll try to keep it in mind as I continue the errmgr work. I gather these tests
all call MPI_Abort?

With our MTT testing we have noticed a problem that has cropped up in the
trunk. There are some tests that are supposed to return a non-zero status
because they are getting errors, but are instead returning 0. This problem
does not exist in r23022 but does exist in r23023.
One can use the ibm/final test to reproduce the problem. An example of a
passing case followed by a failing case is shown below.
Ralph, you want me to open a ticket on this? Or do you just want to take a
look. I am asking you since you did the r23023 commit.

This test should generate a message about MPI is either not initialized or
