""" 
python-xlib's Xlib.display.next_event() does not have a timeout when waiting for an event to be queued.
It may block the script's execution forever.

Workaround:
Call display.next_event() only if an event is available in the queue.
Use select.select() on the xserver's socket to wait for an event and specify a timeout.
