ssh from-other-machine killall -INT X; is the only way to do it because X
is blocked waiting for an event /dev/dri/card0.

It's a consequence of handling zaphod and trying to drain all in-fligh DRI2
events to paper-over a crash should one arrive after the Xserver has freed
all Resources without calling the destroy handlers...

Any non-blocking read on /dev/dri/card0 will block without patches...
