It's always good to celebrate a success story.  In my rõle as the
perennial SCHED_ULE kvetch, I can now add that the key to success in my
case of running "make buildworld" while misc/dnetc is running is to set
the idprio of dnetc to zero.  With that setting, the SCHED_ULE time for
buildworld is finally comparable to (in fact five minutes better on this
particular run than) SCHED_4BSD.

Hmm, what should I kvetch about now?                    -- George
