I'm not sure.  If a test times out and Nagios tries again 10 seconds later 
instead of the 60 seconds specified, that could cause problems; load related 
problems when you have many of these tests running and timing out and problems 
for the system under test not having sufficient time to recover before the 
next check is done.
