Stupid me ran glxinfo over an SSH session with X-forwarding :)

$glxinfo | fgrep 'OpenGL'
IRQ's not enabled, falling back to busy waits: 2 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: Mesa DRI R600 (RV730 9498)  TCL
OpenGL version string: 2.1 Mesa 7.11.2
OpenGL shading language version string: 1.20

Low and behold busy waits are enabled.

Sorry for the noise,
