yes, that seems possible though I couldn't reproduce the exception. I'm 
trying to find a solution, which is a bit difficult as we have to avoid 
deadlocks ...

What I would like to know is: have you tried this with other versions 
than the 1222 development build? Did it work before? I made some 
modifications concerning locking and I'm not sure if I changed something 
that affects the collection locking.
