The simple version that gets most of the way there is (roughly)
if (expose->count) { free(xev); continue; }
since the next event is guaranteed to be an expose of the same window
whenever expose->count is not zero.
To get a fully equivalent implementation, you'd keep a list of unique
windows to expose, and repaint them when xcb_poll_for_event returns
NULL. I'm not sure that's worth the effort.
