Thank you, Daniel. This specific info destroys my idea:

The rest of your comments do not apply. The threaded swap wait is an nvidia proprietary driver only code path, emulating the intel extension glx_intel_swap_event. So changing only that does not influence the nouveau code path or any other driver's one. This specific path already contains a glFinish, so I was talking about moving that, not adding another one.
