Same enough. ;)

Indeed. Don't be so surprised though. The code in the plugins is nothing 
short of horrible, and patches to clean it up doesn't appear to be welcome.

If I were you I'd give check_icmp a try. It's much cleaner and much, 
much faster, especially for host checks if you make a symbolic link from 
check_host to check_icmp and put check_host in your host-check-command 
definition in checkcommands.cfg.

Sorry. My bad. Looks like this is a real bug (it must have been newly 
introduced, because I can't remember seeing it in my CVS).
