Never used it.

I think a good use is for a temporary application, in which you know that
it will run and then terminate after a while by its own. This allows you to
put in a dead-man's switch in addition so if it doesn't, then the
application controller will eventually terminate it.

Things I'd consider:

* Investigative applications.
* Applications which should have an upper limit but where the world around
the application might change so the limit eventually gets broken.
* As an extra protection measure on one-off applications

Usually, these parameters have some history inside Ericsson (we needed this
for a project), but I don't know if it is in use in general.
