22	1998/02/11 PH Even overlapped I/O could be simulated by another subsystem
23	thread with a request queue. We'll see if required ...
24
25
26	Flush (flush handle buffer)
27	WaitForSingleObject
28	WaitForMultipleObjects (?)
29
30	1998/02/12 PH IBM and Microsoft disagree about the definition of FILE_TYPE_xxx
31	Interesting, Open32 returns Microsoft's values ...
32
33	1998/02/12 PH Handles should be equipped with a locking mechanism, in particular
34	as we publish a pointer into the handle table via HMHandleQueryHandleData
