Hmm; that's a dangerous situation.

1) Recovery doesn't work - I tried it, and it did at least make the machine
rebootable, but the GPU state was very broken after the reset attempt.

2) An unprivileged user being able to make the system need & fail to reboot by
default is a security issue; couldn't this be triggered by something like
WebGL?
