As you can see I finally found all difference in initialisation order
and behaviour and now duchain works and uses a shared dpointer. I'm
going for the typesystem next.

Howevre I'd like to know: Is there any chance to make duchain a bit less
fragile? I know this might be undo-able and is probably at least hard
due to the multi-threading issues, but I guess somebody starting with
this and getting the order of things wrong would appreciate it if it
wouldn't simply break down in 1000 small pieces on him :) Without a good
hint as to why it falls apart.
