  Log:
  Potential fix for races shutting down callouts when unloading
  the module.  Previously we grabbed the mutex used by the callouts,
  then stopped the callout with callout_stop, but if the callout
  was already active and blocked by the mutex then it would continue
  later and reference the mutex after it was destroyed.  Instead
  stop the callout first then lock.
