Log Message:
Fix a potential race between drawing and discarding last buffer.

If the last is freed while the screen is being updated, and the use
after free bug is not detected, corruption could occur resulting in
bad areas of the screen that persists until the window gets an
expose event again, or the impacted pixels are updated again.

Possibly fixes an issue reported by nelgin via IRC.
