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.

mpirun noticed that the job aborted, but has no info as to the process
that caused that situation.
