Where's the 64k limit in Linux 2.0.x?  I see on a 2.0.38 system that
uid_t eventually boils down to an "unsigned int", which on any iX86 I've
ever met running Linux will mean 2^32 possible users....

This particular Linux system doesn't seem to have any way to store user
information except in a flat /etc/passwd though, so there may be some
issue with scanning the passwd file, though last time I did any similar
tests there wasn't anything to notice until well after 100,000 entries.
