+   pseudo-handle, DuplicateHandle (GetCurrentThread ()) returns a handle that
+   must be closed afterwards, and there is no function for quickly retrieving
+   a thread handle from its id).
+   Why not the thread id?  I tried it.  It did not work: Sometimes ids appeared
+   that did not belong to running threads, and glthread_join failed with ESRCH.
