Look at implementation of #valueWithin:onTimeout:

It relies on signalling a TimeOut to activeProcess...
So it is not re-entrant :
- the first TimeOut is signalled by inner watchdog after 2 seconds.
- it is caught by inner valueWithin:onTimeout: wich starts the second
inner iteration
- the second TimeOut is signalled by inner watchdog after 3 seconds (1
second later)
- it is caught by inner valueWithin:onTimeout: wich starts the third
inner iteration
- the third TimeOut is signalled by inner watchdog 2 seconds later
(after 5 seconds)

Maybe #valueWithin:onTimeout: could be rewritten susing
Semaphore>>waitTimeoutMSecs:
