  Modified files:
    sys/kern             kern_intr.c 
    sys/sys              interrupt.h 
  Log:
  - Remove the global ithread_list_lock spin lock in favor of per-ithread
    sleep locks.
  - Delay returning from ithread_remove_handler() until we are certain that
    the interrupt handler being removed has in fact been removed from the
    ithread.
  - XXX: There is still a problem in that nothing protects the kernel from
    adding a new handler while the ithread is running, though with our
    current architectures this is not a problem.
