@sam,
I have been running Maverick since Alpha 1. Initially with the bleeding edge X but since Alpha 3 with the "default" X environment. I have replaced Lucid with Maverick due to this bug and I have to admit that (besides a few "bumps") Maverick has been much more stable than Lucid ever was on my desktop.
So from my perspective it seems that they have it under control in Maverick.
