the overlapped in the _cache dictionary, even if we already got the result. We
need to keep a reference to the overlapped object, otherwise the memory may be
reused and GetQueuedCompletionStatus() may use random bytes and behaves badly.

There is still a hack for ConnectNamedPipe(): the overlapped object is not
register into _cache if the overlapped object completed directly.

Log also an error in debug mode in ProactorIocp._loop() if we get an unexpected
event.

Add a protection in ProactorIocp.close() to avoid blocking, even if it should
not happen. I still don't understand exactly why some the completion of some
overlapped objects are not notified.

that we are scanning for the output marker.  If we don't find it, we will
scan them again, so it sees them twice, and it can get confused (like
thinking we're still in a comment).

2009-02-02 51562 (27c589f09a21) merged Mac support revisions into 3.0.
2009-03-04 52014 (dc3d24824b60) merged slightly improved version into 2.7.
Change 3.4+ to match the later 2.7 patch.  Buttons tested manually.

* Tulip issue #196: IocpProactor._poll() clears the reference to the
  overlapped operation when the operation is done. It would be better to clear
  the reference in a new _OverlappedFuture.set_result() method, but it cannot
  be done yet because of a weird bug.
* BaseSelectorEventLoop._write_to_self() now logs errors in debug mode.
