Suffers from the very problem, the OP was trying to avoid: A quite great
delay between the death of the specific process and the monitoring tool
running the check and thus noticing the dead process. Iirc, nagios uses
even higher intervals than one minute between checks.
I guess, the OP wants something like inotify for processes: Passive
checking, yielding an _immediate_ notification about state changes, without
the unavoidable latency of active checks as nagios performs them.
