get objects referencing another one

[Olivier Feys]

I'm working on a tree and I have refcounting problems.
Is it possible from an object, to get the list of objects referencing it ?

thanks

The gc-module might help, but it is somewhat overwhelming.

Another solution may be to use weak references:
