Yes, most file numbers are unchanged.  I think the problem is that
CREATEPROCESS does not pass on any file descriptors except, I think, stdin,
stdlist (stdout), and stderr.

Contrary to your earlier message, fork() and exec() are not implemented with
MPE intrinsics (i.e. not ones an ordinary program can call).

I think your best bet is IPCGIVE/IPCGET.  I think it's been stated on this
list before that you can use these with Berkeley socket fds.
