The signal handler that Darius mentioned should work. It's just that if 
you are using SIGUSR1, you cannot overwrite what is set by MPICH2. You 
need to chain them, i.e., override the signal handler, do whatever in 
your signal handler and then call the old signal handler once you are done.

I'll let Darius answer this.
