[Bug 36692] Bad performance when combineng SetEvent / WaitForSingleObject for synchronizing worker threads

--- Comment #6 from Vincent Povirk  ---
DuplicateHandle can still pull an anonymous event handle out of another process
and start using it.

So, you either need the server to be able to tell the process that controls a
handle that it's being moved into the server, or you need a more efficient way
of doing this that works across processes.
