Oops, I should have read the whole thread before posting my previous
e-mail. :-)

Well, if we don't have a myAppIsRunning() API, apps can simply busy-loop
whenever they want, so I don't see much harm in adding this API.
We could also protect it with apparmor, so that the usage of this API
must be explicitly declared in the application's manifest file (and then
we could question whether the app has any reason to use it).

Note however that this would still solve the issue of detecting apps who
use too much CPU time because of some bugs, which I think was the
original goal.

Ciao,
