--- Comment #13 from Uli Schlachter <psychon at znc.in> ---
So the backtraces (which are a mess) say that there are just two threads
running code inside of libxcb. One of the is sitting in xcb_wait_for_event() ->
poll(), the other inside of xcb_wait_for_reply() -> pthread_cond_wait(). This
seems valid and thus I guess that the bug is inside of the server. Let's see
what they think.
