Kernel - Instrumentation for experimentation, interrupt threads
* Add kern.intr_migrate (default off). If set to 1 interrupt threads
will chase the big giant lock around the cpu space instead of waiting
for another cpu to release it.
* Add lwkt.bgl_yield, default 10 (uS). Set the polling delay when
yielding the BGL to another thread.
