Sebb commented on EXEC-106:
---------------------------
Huh? I don't think it's *necessary*; the current synch. works as far as I know.
However if volatile is sufficient, it should be cheaper and simpler than synch.
[AFAIK the code was originally written before Java 5 so using volatile was not
an option then.]
> Watchdog class could use volatile instead of synch

> It looks like the Watchdog class could use volatile for the boolean field
> 'stopped' instead of synchronising.
