You probably don't need active host checks since Nagios already checks
hosts on service state changes. If you really need to check ICMP then it
would be much better to:

1. Make your host check perform 1 ping and return asap (on demand host
checks)
2. Add a service for ICMP checking where you can take as long as you
wish to perform the check (obviously, a different check_command).

Nagios 3 can parallelize scheduled host checks and allow host result
caching to overcome these limitations of Nagios 2.
