Uhm. I do not know, looking at the code and what Xlib does ended up
confusing me some more. Right now I see no reason why
xcb_discard_reply() would not work, but I haven't really checked this
properly.

How are you handling other replies that the requests that you send
generate? Can't you generate the GetInputFocus reply the same way?

Also, why do you need to take the socket at all? Can't you just use xcb
"the way it is intended to be used"?
