No effect.

After llvm,llvm-libs update 3.4.1 -> 3.4.2 also glxgears starting to freeze
instead of normal exit by ESC:

Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
2469 frames in 5.0 seconds = 493.688 FPS
2476 frames in 5.0 seconds = 495.177 FPS
