  Log:
  Interrupt thread preemption was switching in threads with held tokens
  without acquiring the tokens.  Just don't preempt if the target thread
  is holding a token.
  
  This fixes a token-related panic when using the NDIS driver.  NDIS
  is the only driver which uses tokens in its interrupt handler.
