kcachegrind screenshot: _mesa_FenceSync

I ran callgrind on Bioshock with mesa-git.

Callgrind instrumentation was enabled only when the Bioshock benchmark was
rendering frames from the game. The benchmark graphics quality was set to
Medium.

The screenshot I am sending indicates that Bioshock expects a faster
_mesa_FenceSync implementation.
