App watchdog / kill frozen apps

[b0xcat]

I was talking with @hughrawlinson and the question came up if we should somehow try to prevent apps from locking up the entire system if they get stuck somehow.

As a simple example, lets say we have an app that does something like this:

def update(delta):
   while True:
      pass

It would block the event loop and prevent the badge from doing anything else until it is reset.

Maybe we can spin up a thread with a watchdog somehow to prevent this? Or is this something we shouldn't worry about?

Perhaps asyncio wait_for could be used for app updates?
