  Log:
  Always explicitly panic in propogate_priority() if we try to propogate
  a lock's priority to a sleeping thread.  When we panic, dump a stack
  trace of the thread that is asleep if DDB is compiled into the kernel
  just before calling panic().  This is much more informative and useful
  for debugging than the current behavior of getting a page fault and not
  having an easy way of determining which thread caused the original problem.
