QWinOverlappedIoNotifier causes a memory leak

QWinOverlappedIoNotifier causes an increased memory consumption (a memory leak?) when are used the blocking waitForXX() methods.

How to reproduce (see also an source example from an attachment):

1. Create the QWinOverlappedIoNotifier and make connection to the notified() signal.

2. Open some file to read by CreateFile() with the FILE_FLAG_OVERLAPPED flag.

3. Set a file handle to the QWinOverlappedIoNotifier instance

4. Call the ReadFile() to try to read an one character from the file.

5. In the forever cycle call QWinOverlappedIoNotifier::waitForAnyNotified(-1) method

6. In the notified() handler call the ReadFile() again.

Open the TaskManager and watch for the memory consumption .

UPD the example need to run with specifying a full path to a file wchich need to read, e.g.:

overlapped-notifier-bug.exe <path-to-any-file-to-read>

PS: This (bug?) eats all memory..
