If you really want a cookie queue, please use the xcb_reply library and
we'll fix the performance later. It'd be easy to implement a ring buffer
under that interface, for example.

I provided both a multi-thread and a single-thread interface to that
library. In a single-threaded application you can just periodically call
PollReplies. As currently written, xcb_reply will pull in a dependency
on libpthread even though you're not using it, but we can fix that
later.

I claim that an event handling thread, and even a reply handling thread,
are really good ideas. But XCB and the xcb_reply library are designed to
allow you to disagree with me.
