Julian,
if we agree on this, I am fine.
(This implies that SCHED_4BSD will *not* be retired for an
indefinite time!)
There is no reason to retire it.
We implemented a scheduler interface that both schedulers stick to.
I tested yesterday, and SCHED_4BSD doesn't show the annoying behaviour.
SMP seems to be no problem (and I need that), but PREEMPTION is
definitely related to the problem (see my other message sent now).
