Hm, that means as long as I realy don't look at the data of the parent
the data is shared between parent and child. Thats funny - it's a
useless feature. As soon as a child reference that dictionary  it gets
it's own copy. 

What about shared memory, is it possible to put objects into a shared
memory segment, most advanced language can do that?
