This would let you do a constant-time context lookup, but if that's your performance problem you have two problems. Just use the context's XID as the tag value instead. In order to do this, we have to defer destroying a context until it actually goes unreferenced, as you're allowed to mention a context tag after you've (ostensibly) destroyed the context, as long as it's still your current context. Thus, change DestroyContext to merely mark the context as dead if it's a current context, and call down to actual resource destruction (and XID reclamation) in StopUsingContext. Also, stop trying to delete context state from DrawableGone. This was always broken, as GLX does not say that contexts are destroyed when their drawables are destroyed. But with the above change to defer context destruction, this would trigger a server crash on client exit as we'd free the context state twice.
