Windows is loaded with async/event/callback stuff.
I'm no expert for sure but here's some code that worked well.
It wakes up when a file is modified.

Look for this snippet.
    hnd=win32file.FindFirstChangeNotification
(......FILE_NOTIFY_CHANGE_LAST_WRITE )

    int = win32event.WaitForSingleObject( hnd, -1)
