OK, I have refined this so it's much more useful. The idea is that
*if* a icmp ping test is used in a check host entry, this test is run
first. Now, if the ping test should fail we assume that the connection
to the host is down and monit does *not* continue to test any port
connections. This means that you do not need to use unmonitor and
stuff like that, the whole thing is automatic. Here's an example:

 check host xyzzy with address xyzzy.org
       if failed icmp type echo with timeout 5 seconds then alert
       if failed port 80 proto http then alert
       if failed port 443 type TCPSSL then alert
       alert address@hidden

In this case, if the icmp test should fail you will get *one* alert
and only one alert as long as the host is down, and equally important,
monit will *not* test port 80 and port 443. Likewise if the icmp ping
test should succeed (again) monit will continue to test both port 80
and 443. 

I have put up a new monit 4.1 beta2 with this feature and you can read
about the icmp ping test here:
