Apologies for being so slow to look at this.

Unfortunately I think it's incorrect.  lastGLContext is not necessarily
of __GLXcontext type - glamor sets it a glamor_ctx *, for example - so
passing it to ->loseCurrent isn't always going to work.

I think your first patch that only did the loseCurrent from
__glXForceCurrent was closer to correct.
