Comment 4 for bug 390552

It's been a while since I submitted this so I'm not sure exactly what the
situation is, but I can say that Windows supports key-release events *WAY*
better than X11. X11 pushes a fake key-release event into the X event queue
for autorepeat. Windows only issues a key-release event when the physical
key is actually released.
In windows, it is easy to detect an actual key release event. In X11, it is
much, much harder.
