Here are some patches for win32-service which eliminate the messy busy loop that polls the hStopEvent with a zero timeout.
Instead of using a Windows event, these patches create a UDP/IP socket bound to the loopback interface which can be
used in ruby's green  threads event loop.  I believe this is a much cleaner and more efficient mechanism than the WIndows
event flag since it allows the ruby thread to block until there's really a control event from the WIndows service
manager.

I also include a hCtrlEvent event flag which can be used by ruby win32 services which must wait for control events.
This event handle is accessible via the daemon.event_handle method.  Note that the hCtrlEvent is not used by the daemon.c
logic, it's merely an event which can be used by the Daemon subclass.

We've been looking at this implementation again, and Park has
implemented a version in pure Ruby.

The downside, at the moment, is that there's a socket bug in
the one-click that would make this problematic.

I haven't yet had a chance to seriously review this but I definitely
haven't forgotten it!

Thanks,
