Huh, that's strange, never crashed on Linux.  :/

Yeah, this is a bug in SDL2 at the moment on Windows. The XInput API 
(which a 360 controller would use) doesn't offer a means to specify a 
timeout, but manually stopping the rumble works.

Your fix is good in any case, but I'm planning to fix this in SDL2 this 
week, too.

I would like to do this. Even ignoring all the really good improvements, 
I'd love to fix the double-Li bug on Steam if nothing else.  :)

I think between you and Andrew Church, we've probably got 90% of the GPL 
work. Andrew, are you interested in this?

If we're all cool with that, I'll check with Alec to see if he'll let me 
update the Windows Steam build too.
