What happens if 30 seconds are not enough for the cleanup ? I suppose
we already handle that (as we can already interrupt the build at any
point), and the next build will already clean up whatever mess what left
behind. If that's indeed the case, then the --kill-after=30s looks a
bit useless, we should just abort the download and move on with the
next step. Indeed, saying "30 seconds should be enough" sounds like
saying "640 KB of memory should be enough" :-)

Best regards,

Thomas
