From 794c81c1eab54cb58f2143ab3efc90e9c4bf9092 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Samuel=20R=C3=B8dal?= Date: Thu, 25 Aug 2011 13:39:07 +0200 Subject: Move XCB event reading to a separate thread. Work-around for bug in XCB which causes a xcb_wait_for_reply to block if xcb_poll_for_events() is called simultaneously from a different thread. If the XCB version is too old this work-around causes even more problems, so we kill two birds with one stone by only using the work-around if the XCB version has the recent xcb_poll_for_queue_event() function, which we also need to read events from a separate thread with reasonable efficiency.
