Modified Files:
src/sys/rump/librump/rumpkern: scheduler.c
Log Message:
Increment lwp's context switch counter when it is scheduled onto
a CPU. This fixes some heavy-load problems with the pool code when
rump kernels essentially lied and caused the pool code not to do
a proper backdown from the fastpath when a context switch happened
when taking a lock.
