i suspect a single bit would be sufficient to distingush between pag's
and uid's?  it does appear to be encoded in the pag and is used as
some sort of check to see if the value derived from the groups is a 
pag.  perhaps i dont understand afs_get_pag_from_groups().

well i guess the range would just grow.
