Okay, avoid! First I thought it works, but now it doesn't: so if it worked at all (was quite tired when I tried it), its absolutely unreliable.

For the record: I moved to a different approach: 

1st) cache my persistent entities
2nd) detach from them
3rd)  work on the cached state, update them as I need to (even from different threads)
4th) update the cached state periodically with a Timer

Thats accurate enough for me and I can react on events like callbacks immediately.
