Gracefully Handle Background Task When App Tombstones

I'm using the async ctp and have a task that runs in the background. It works great but throws an exception when it's running and the app is tombstoned. The exception is related

Solution 1:

We also had a number of problems with this, but the general architecture of a mobile app tends to be service oriented so most people will not have to worry about database connections. Handling tombstoning is error prone in general - this area was one of the prolific bug generators in my project.

It is OK (not great) as a user experience to return to the start screen after waking up from tombstoning and not to the last screen. Otherwise you could cache the data you already have - using the IsolatedStorage and try to redo the screen.
