Hmm...even if I get my number of groups low enough, the 95 usrmgr still
complains.  I get the entire list of user names showing, and at least all
of the groups I have in /etc/group, but not the other "standard" groups
(Administrators, Backup Operators, etc.).  That list is always "too long".
The NT/2k usrmgr handles the buffer overflow problem and reads off the pipe
following the call.  The 95 usrmgr just gives up when it doesn't get it all
in one response.  I don't see (for what that's worth) any way around it....
