If you have kernel source, there is a hack of a few lines done by
Berkeley Computer Center that sez if uid == gid then the user is
considered the "group master" for the class (group) and has all
privileges over files in that group.  So it doesn't depend on the
directories having the "right" protection mode and the umask being
right.
