automatic renice in 4.1 bsd?

[Jeff Anton]

If I remember 4.1 correctly it will move the nice of a process
from 0 to +4 after 10 cpu minutes.  This only applies to
non-root and nice = 0 processes.  Csh however has a bug in the way
it handles the 'nice' internal command.  Csh attempts to set the
nice absolutely by doing the nice +40 then nice -(20-resultnice).
This however, fails if you are not root and will set your shell
to nice +19 (The real maximum).  The fix is pretty easy.
You should go into csh source and change these nices into a call
to the new setpriority. (I think it's in 4.1)

Disclaimer: I don't work on BSD, I just know a few pieces of it. (bugs)
