Ah, maybe, my bad -- I read xcb_property_changed() and saw no
GetProperty request. Actually the request is made in call_handler()
which is probably inlined and invisible in the backtrace, that's why I
was wrong. :-)

So yes, it might hang in xcb_property_changed(), but as far as I can
tell, we never saw such a problem and considering what's doing
xcb-property, I doubt it's the cause. :-)
