In a job a long time ago in a place far far away ....

I set the nice value of login to be 2:  I.e. just before login
does the setuid stuff it does nice(2).

Hence the default level of all users was 2.  Then the cc system
and nroff/troff had a nice of 3 set (actually one should nice to
max(3, current nice).  And all editors had a nice of 1.  Ps ran
with a nice of -10.

The result was that interactive users got good response and
nobody suffered.  Even with the new UNIX schedulers this scheme
ought to be adopted by all.
