I find it hard to believe that handling 100,000 users on one box is a good
idea in the first place.

So with your setup, any user can add/delete/modify existing users?  Yeah,
that's secure.

Yes, but with 100k+ users, a database (that requires slow rebuilding) is
faster to find random records in than a flat text file.  In fact, perhaps
you should have instituted some sort of cron'd rebuild (once every 30
minutes for instance), and then queued the changes, so as to prevent users
from frobbing in an incorrect manner.
