eliu兄好：
最近這幾天gcin有時出現莫名其妙的錯誤（或莫名crash），一時還找不到可重現的規則，
偶然可以從終端機看到一些重複出現的錯誤訊息，希望可以提供一些線索：
gcin: ../../src/xcb_io.c:274: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.
gcin: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.
[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
