Cool!  Thanks.  If you would in particular let me know the general approach
you'd like to see taken to address the issue in the "group" case, I can write
the patch if you're pressed for time.  I just need to know whether it'd be OK
to just open the file each time with the nam/gid calls, or whether you feel the
documented optimisation is still important, in which case, a bit more surgery
is required in the "ent" iterator to save/restore file offsets.
