Are you sure that this works like --host-timeout is supposed to? Note that --host-timeout is supposed to expire the whole host after the given amount of running time for that host has passed. So if 9 minutes have passed in port scanning, the host only has 1 minute left. While another host (which finished port scanning more quickly) may still have 5 minutes left.
Oh, and the patch removes the minimum time check for the --host-timeout option (but still gives a warning if it is below 15 seconds). It is helpful for testing and I think
That is fine for testing, but it is important for the official version. Otherwise (even when there was an error message saying the option shouldn't be used so low) I got a bunch of mail complaining that 5 second timeouts (and the like) didn't work they way they expected them to. Also, people specify things like 600, thinking it is in seconds and they are getting 10 minutes, but really they get 6/10 of a second. They might not see a warning message before it scrolls off the screen, but the fatal error message is crystal clear.
