Understandable - and we can count on your patch in the near future, then? :-)

Basically, the user has an application where one process decides it should cleanly terminate prior to calling MPI_Init, but all the others go ahead and enter MPI_Init. The application hangs since we don't detect the one proc's exit as an abnormal termination (no segfault, and it didn't call MPI_Init so it isn't required to call MPI_Finalize prior to termination).
