Modified files:
sys/kern kern_subr.c kern_synch.c
sys/sys proc.h
Log:
Improved scheduling in uiomove(), etc. resched_wanted() is true too
often for it to be a good criterion for switching kernel cpu hogs --
it is true after most wakeups. Use the criterion "has been running
for >= 2 quanta" instead.
