The problem here is that the threads in this case are MPI threads, not
threads spawned during execution. (mpi4py).  I want exceptions to be fatal
as they normally are, but it *must* call MPI's Abort function instead of
just dying, because that will strand the rest of the processes and cause an
infinite hang if there are any subsequent communication attempts.

Hopefully this explains it more clearly?

Thanks!
