The answer to your question:
the typical use is something like this:
if (session.isNew()) {
// store listener object in the session.
}
Now your Listener will be called when the session
is started (valueBound()) and when it ends (valueUnbound()
that's the one where you could kill the jobs)
To find out the number of active session you have to
implement a Listener as above that increases an 'global'
var with every valueBound() and decreases it with every
valueUnbound().
