This may present a serious design problem. Let's say Event A happens, so your script runs and sends out an email about it, then sets a flag somewhere to say "Don't send any more emails for one hour." Five minutes later, Event B happens. Now people won't get notified about Event B until at least 55 minutes later when the next email is allowed.

That may not be acceptable in a "near-real time detection system"; and if it is acceptable, then it should be acceptable to run the script hourly. Either way, you're going to have notifications up to 1 hour old.
