Yes, i had already thought of that too. I was wondering if 
when forrestbot starts we can create a flag file in the
forrestbot-logs directory, which gets removed at the end
of the process. I have started a coding experiment.
We would probably also need a way to check if there was
a stale flag file lying around.

Yes, the more in there the better.

I will try that in my next free time.

I am afraid to add even more to the cocoon build procedure.
It is already so complex. But yes, that might be a solution.
