Ivelin, could you clarify a little bit [1]? If I understand periodically run and time 
the execution of a certain task. If it takes too long to execute (for a consequetive 
number of measurements) then broadcast a notification.

What could make a suitable task? It could be configurable (e.g. execute a syncronous 
operation on some other MBean), still, what makes a good task?
