True. I suppose we should fix that in remove_lock_file_on_signal() as well,
then? It does exactly the same thing.

SIGINT was bothering me the most, because I often kill http-push by pressing
Ctrl+C. I also considered adding SIGQUIT, but decided against it because
normally I press Ctrl+\ only if I want the program to quit _right now_ and
Ctrl+C does not work. On the other hand, sending the signal twice will
terminate http-push either way.

I don't know in which situation SIGHUP would come into play.
