Someone at inmet should look into installing the current version
of notesfiles, to help eliminate the `Orphaned Response' plague.

If you intend to set both user and group IDs, you should do this in
the other order.  This is likely to work for tip (which is not setgid)
or under 4.2/4.3BSD (where setregid allows either egid or rgid to
be specified for both), but breaks on V7ish systems (including 4.1BSD).

As to the original bug, I have no idea what is wrong; we do not use
tip.
