The tests I've added clearly show that user APCs are not supposed to be
executed during GetQueuedCompletionStatus call, so my patch is wrong in
that regard. On the other hand it looks like the queued APCs are never
executed (and nothing in the attached application breaks) means that
adding an APC to the queue as a reply to APC_ASYNC_IO request and actually
executing it wasn't tested very well (if tested at all). So it raises
a question whether APCs should be always generated by server, or generated
at all.
