This would be enough?

  Pacing delays are measured from entering the pacing code till exiting it. Therefore,
  observed pacing delays may be higher than the threshold when paced thread spent more
  time in the pacing code. It usually happens when thread is de-scheduled while paced,
  OS takes longer to unblock the thread, or JVM experiences the STW pause.
