Error Handlers Function

[Barry Smith]

    This is an MPI question and has nothing to do with PETSc. Perhaps  
there are some MPI mailing lists out there for this type of question.
Note: I don't think exit() is something that all MPI implementations  
can catch and distribute to the other MPI nodes, but this is something  
MPI folks would know.
