* we do this in a separate thread so that:
* - we aren't bound to when the app chooses to pump the event queue.
* - we aren't adding more polling to the event queue
* - we can emulate all the haptic effects correctly (start on a delay,
* mix multiple effects, etc).
*
* Mostly, this is here to get rumbling to work, and all the other features
* are absent in the XInput path for now. :(
