Yes, and ultimately not only to get rid of the TSX functions but of all the explicit X11 locking too. These days I think it's reasonable to assume that the X libraries are thread safe.
This means that I will have to change the usage of the X11 critical section in the D3D code by one of our own (basically, we 'misuse' a bit this crit. section to prevent two threads doing GL calls at the same time - something that games like DungeonSiege love to do :-) ).
