  I agree an OS should deal with CPU scheduling, but I don't think that
it would be prohibitively difficult to support background compilation.
Judging how often to yield CPU time might entail a little bit of work,
but it seems obvious to me that they are already checking for events,
since they catch cmd-'.' to interrupt compiling.
  I s'pose the main difficulty would be ensuring the foreground process
regular CPU bursts. However, I think it would be relatively simple to
add some code around the are that provides status updates ("xxx lines")
that looks at the current number of ticks and calls WNE() after a
reasonable amount have gone by.
  There are two reasons I see to provide this feature: (1) you can read
the netnews while you compile :-), and (2) you can start fixing the
errors that are showing up in the "compile errors" window. :->
