I have ported a program that makes extensive use of the Unix signal facility
to Mach.   Now I need to modify the program.  The modification requires the
use of Mach exceptions.  However, I'd like to change the program itself as
little as possible.  In particular, I prefer not to modify the signal
handlers.  Is there a way to catch the Mach exceptions that I require in an
exception handler, and pass the rest back to system to be redelivered to the
program as Unix signals, i.e. is there a way for some exceptional conditions
to be processed as Mach exceptions and others to be processed as Unix signals.
