I disagree. Having the activities save their state automatically on 
closing is important for not losing any work done by the user. And while 
we should optimize activities to not save during their runtime (i.e. for 
window switches) if there hasn't been change since last save, we need to 
at least update the timestamp on close.

If we compare our system to "real" activities, deleting a Journal object 
that is still open doesn't make a lot of sense: It's like throwing a 
painting into the garbage while you're still drawing on it.

To get our model back in sync two options come to my mind:
1. Prevent deletion while the activity is still running.
2. Automatically close the running activity (on switching away from it 
we have saved, so there are no unsaved changes left to write on closing 
it).


Originally I preferred #1, but maybe #2 makes more sense to the user. 
Just hope nobody "discovers" it as a way to close activities (especially 
depending on the particular translation of "delete")...
