Didn't Kristian do a bunch of work done time ago to make mutexes faster by
not using pthread on Linux? If so, this should be an unnoticeable
performance improvement.

Kristian did a bunch of work that never landed. krhmutex~1 of my tree
has his patch - IIRC it got review feedback that was never addressed.
I took a quick look. Seems everything got addressed besides the clashing
with C11 [1].

Someone should probably revive that. radeonsi might get more of a boost
at this point...
Should be fairly straight forward task if someone wanted to take a look,
its the second and third last patches [2]. I suspect the draw overhead
piglit test should show some improvements if we are going to see any [3].
