Yup. Nagios doesn't delay sending the host-notification until it has 
checked parents, so sometimes excess notifications are sent out. The 
theory is 'when in doubt, get it out' (which also conforms to parachute 
malfunctions but not the sexually perverted).

I'm working on a quicker way to do this for the entire route (moving the 
parent-checking logic somewhat out of nagios) in no-time, but I need to 
bring it up with Ethan before I actually commit myself. I hate it when 
good work's being thrown to waste.
