XSLTProcessorImpl uses Store.TRANSIENT_STORE, like the FragmentExtractor. I 
haven't mentioned this explicitly.
I have looked into the interfaces, and when I understand right, I had to look, 
if store implements ThreadSafe. Store doesn't implement ThreadSafe, but the 
MRUMemoryStore, which is used as default in cocoon. So I'd say it's a bug in 
XSLTProcessorImpl. Agreed? What I would do, is asking in avalon-users for 
changing XSLTProcessorImpl and perhaps others or to have Store implement 
ThreadSafe. But I guess, Store is already released.

Domain in provider transition, hope for smoothness. Planed date is 1.7.2003.
