I'm afraid that one also escaped my attention (I should really try to keep 
up with the list if I insist on using -CURRENT, I suppose!)  I'd managed 
to get the impression that SCHED_ULE was the "way ahead", and I suppose I 
may as well keep it in there unless it becomes a major problem, but I can 
live without PREEMPTION so I'll lose that.

I'll give it another recompile without PREEMPTION (and, if that doesn't 
fix it, with SCHED_4BSD instead of _ULE) and report my findings.  But I'll 
do that tomorrow as it's now 4:30am and I'm feeling a bit bleary-eyed...

Chris.
