Ilia, Peter.

I've filed a bug for you here : 
https://bugs.freedesktop.org/show_bug.cgi?id=91535

I've verified that Peter's PPA library when installed fixes the race 
condition you guys were talking about but running the test program 
tests/nouveau/threaded so, this issue we're discussing here is a 
separate one.

Cheers,
Bryan
