Comment (by simoncperkins@…):

 Ok, thanks for fixing the problem but as stated above I disagree with your
 points.

 I believe you can safely free the overlapped structure in 2) if the IO in
 1) has completed. That's how IO completion ports are intended to work.

 The current implementation is sub-optimal because it makes unnecessary
 calls to PostQueuedCompletionStatus .
