The problem is that mesa install atexit handlers to shutdown EGL, IIRC the original problem was that we were getting crashes when EGL was uninitialized by mesa because we had already destroyed things. Just by adding our own exit handlers things happened earlier and crashes didn't happen. I don't remember the details, but I think it was something like this.
