caused hangs on SMP systems under load.  My theory was that an interrupted
thread was migrating and returning to PAL on a different CPU and that that
caused the hangs.  To prevent this, I used the recently added sched_pin()
API to pin the interrupted thread to the CPU that received the interrupt
across ithread_schedule() to prevent migration.  This seems to have fixed
the hangs based on tests by several folks on the alpha@ list.

Tested by:	wilko, tisco, several others on alpha@
