Thanks for the pointer but I don't understand why you think this solves
the problem.  I am actually already using the techniques mentioned here
but, regardless, cygwin has never had any problems maintaining a
parent/child pid relationship.  My changes don't affect cygwin's
existing mechanism at all.

If there was some method for ensuring that a new process had the same
PID as a previous process, that would be great.  This article does not
seem to document anything like that.
