Thanks Harald, this sounds reasonable.  I'm not sure what to do if
autoconf detects that the system is missing a setregid() though.
Right now it just doesn't get called.  I suppose I'll also document
all this in the FAQ.  I tested this on Wes' machine with my example
code, and it looks at least like the popen() process is getting the
necessary gid.  I did not test it with a live Mailman setup.

Folks (especially Wes and Edward, and anybody else who was noticing
these problems), could you please wait for my next check-in and then
grab the CVS snapshot.  Reset the ownership on ~mailman/data and do a
re-install to see if my changes fix your problems.  If you can't
access the CVS repository, let me know and I'll do a beta9 release.
