I find it pretty painful to wade through a several-megabyte regression.diffs
to find the cause of a crash. I think we ought to use
restart_after_crash=false, since after a crash there's no hope for the tests
to succeed, but even in that case, we end up with a lot of pointless contents
in regression.diffs. If we instead realized that we shouldn't start further
tests, we'd limit that by a fair bit.
