Are you sure that bash is doing the right thing?  Strace implies that it
is setting the process group of the terminal to a nonexistent pid.  It
is a bug in cygwin that this is allowed but it seems like a bug in bash
that it is doing this at all.

Fixing the bug in cygwin seems to cause bash to behave better but it
still seems strange.  This seems like YA instance of bash assuming that
it can rely on the fact that a recently exited pid will be invalid.

Anyway, thanks for the bug report with simple test case.  The fix is
in CVS.
