Handle drawable destruction and lifetime correctly. Check whether the drawable priv is valid in DRI2SwapInterval(), DRI2WaitSBC() and DRI2WaitMSC(); it may have gone away, so be sure to check it before using it. If more than 1 outstanding swap is queued, we may complete several after an app has exited. If we free it after the first one completes and the refcount reaches 0, we'll crash the server on subsequent completions. So delay freeing until all swaps complete and remove the error message as this is a normal occurence. To do this properly, we must also avoid destroying drawables in DRI2DestroyDrawable() if a swap or wait event is pending. And finally, make sure we free drawables in DRI2WaitMSCComplete() if necessary (i.e. if the refcount has reached 0 and this MSC was the last pending event on the object).

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
