I move this thread to dev@cocoon.apache.org because we're talking about
implementation details.

I think so too.
Currently I'm thinking of a new "BackgroundThreadEnvironment" that will
be responsible for the environment but more opinions on this are
welcome.

(I started with this about two weeks ago and had some problems with the
Context object but I hope I have some more time tomorrow to find out my
concrete problem)
Unfortunatly I can't check in ATM because I'm working in a customer's
office and the firewall doesn't allow SSH access but I'll talk to the
firewall administrator in the afternoon ;-)

Cheers and thanks for your engagement!
Reinhard

P.S. I'm going to add a pointer to the Bugzilla issue!
