Word of caution -- on the off chance you plan on running this on top
of nouveau, don't remove the "-1" flag. There were kernel-side bugs
with multiple processes creating contexts simultaneously up until
quite recently, and even with those fixed, I still get hangs often
enough that I just use single-threading everywhere.

Good luck!
