  Log:
  Fix a token bug.  A preempting interrupt thread blocking on a token cannot
  safely call lwkt_drain_token_requests() because the procedure may give away
  tokens owned by the preempted (parent) thread.  Instead we simply call
  lwkt_yield() to turn ourselves into a normally scheduled thread and return.
