  Your idea was clever, but it introduces a subtle race condition if one server
  is returning from HttpExtensionProc and another is calling DONE_WITH_SESSION
  at the same time.

  The final patch simply creates the completed lock for every request that is
  configured with fake_async and suffers from no race conditions.  Please review
  the module and provide feedback, if any.  Thanks for your report and proposed
  solution!
