Priority shells, do they work?

> Yes you can setup login to give a set of priorities to users.

In fact, the System V Release 2.0 "login" supports his (undocumented, of
course - this *is*, after all, UNIX, home of the useful but undocumented
feature).  Begin the "gecos" field with "pri=<number>" (number may be
positive or negative) and it'll do a "nice(number)" before it asks for
the user's password.  (On a heavily-loaded system you might, admittedly,
be able to use this trick to figure out which accounts exist.)
