Its not really reasonable to handle failures to make_current, it basically only happens if you pass invalid arguments to it, and thats not something we trap on similar things on the X drawing side. If GL is not supported that should be handled by the context creation failing, and anything going wrong after that is essentially a critical (or an async X error).
