Obviously the solution is simple: I've already implemented it.

But seriously? You think a hard Xserver crash caused by a userspace client is
NotABug?

I don't believe that it's reasonable for the Xserver to crash in this fashion:
Refuse to run the application? Sure. Fall back to software rendering? Why not.
Segfault and kill the entire desktop? That doesn't seem very user friendly to
me frankly.
