Thanks for the suggestions. However, I'm happy to see that there is probably
not going to be a need to work around this problem in the near future when
https://bugs.freedesktop.org/show_bug.cgi?id=26394 gets fixed. That should
eliminate the possibility of BadDrawables from DRI2DestroyDrawable altogether.

Patch has been already sent for review:
