* The nsDOMWorkerTimeout has a slightly complicated life cycle. It's created
* by an nsDOMWorker (or one of its JS context functions) and immediately takes
* a strong reference to the worker that created it. It does this so that the
* worker can't be collected while a timeout is outstanding. However, the worker
* needs a weak reference to the timeout so that it can be canceled if the
* worker is canceled (in the event that the page falls out of the fastback
* cache or the application is exiting, for instance). The only thing that holds
* the timeout alive is its mTimer via the nsITimerCallback interface. If the
* timer is single-shot and has run already or if the timer is canceled then
* this object should die.
