--- Comment #1 from Dave Gilbert <freedesktop at treblig.org> ---
I think there's a fair chance that it's actually getting stuck in the while
loop in my ray.comp (which may well be a screwup on my part); but even so
taking out everything in a non-rebootable way is a bit of a mess!

adding:

seems to stop it triggering.
