I doubt that this is the case.

  The IO, including the closing of the connection, is
  handled by the ZServer thread. This is a single thread.
  You would immediately observe should it block (Zope would
  be irresponsive).

  When the connection is closed, the Zope worker thread has
  already been released. By the way, their number is fixed
  (and usually small).
