possibly not.  imagine a situation in which a group enumeration occurs, it
gets group info (members of the group).  the group enumeration could call
getgrent, and the enumeration of the group members could do likewise.

what about getting the primary user's group and the users' group members?
etc.

so it's all riddled with awkward horrible stuff and i'm giving serious
consideration to cacheing the unix group -> nt rid data using
groupdb/aliasfile.c,groupfile.c and builtinfile.c.

the enumeration algorithms for *unix.c are probably order n squared at
least, and for them to be fixed properly then need to be order n cubed,
which is horrible.
