I don't remember for sure, but I believe when we merged
xcb_discard_reply, we decided not to implement support for discarding
requests issued with xcb_writev. That's feasible but requires
splitting list nodes in the pending_replies list. So unless I'm
mistaken, at the moment neither of these patches is quite correct.

I'd welcome either being told that xcb_discard_reply actually *does*
work here, or getting a patch to make it work. :-)
