Bug description:
Geis event dispatching can hang with high cpu usage under some circumstances.

Specifically, if a gesture event callback contains the following sequence

  system("xdotool getactivewindow key x");

the X server sends an XCB_UNGRAB_KEY event, which sends the event dispatch into an infinite loop.
