Ok, this is the oldest pending patch I have from you, and the right fix
is to make the code use the actual process gid rather than the
/etc/passwd entry.  (The setgid bit or setgid() from root could change
that.)

Tightened up the code a bit while I was there.  (There's more cleanup to
do, but I can get back to that later...)
