Yeah. The case I was thinking about was mostly "start initdb,
decide I didn't want to do that, hit control-C". That cleans up
without much fuss *except* if you manage to hit the window
where it's running bootstrap, and then it spews this scary-looking
error. It's less scary-looking with the SIG_DFL patch, which
I've now pushed.
