Note the AsyncResponseHandler suffers from the same issue when used like this:

  f = client.File()
  handler = AsyncResponseHandler()
  status = f.open(smallfile, OpenFlags.READ, callback=handler)
  status, response, hostlist = handler.wait()

This is because the callback is defined as:

  def __call__(self, status, response, hostlist):
    self.status = status
    self.response = response
    self.hostlist = hostlist
    self.mutex.release()

The file above may be closed in the main process any time after mutex.release() is called; however, the callback will still need to hold the GIL to exit the function. It would be quite hard to trigger in this case, however.
