  I don't *think* any of the changes to threads.c would cause this
problem.  But that message is produced only when the request queue is
full.

  i.e. new requests are coming in faster than the server can process them.

  Yes.  It tries to exit cleanly, but something calls request_free()
on a request currently being used by a thread.  The solution to that
problem is simply to *not* call request_free() when exiting.

  As for why it's blocked, see the rest of the debug log.  It *should*
tell you what's blocked, and where.
