[Algorithms] Circular References

[Julien V. L. <van...@ya...>]

Hi,

I'm interested in system which can deal with circular references (object A
has a reference on B, and B has a reference on A => A can't be destroyed
because B has a ref and B can't be destroyed too cauz A has a ref).

I've read a lot of papers on Garbage Collector and ALL say that circular
references is a BIG problem with reference counts cauz the system can't deal
with it.
But I've never found a system able to do it !! Does it exist ?
Don't say stuff like "just use weak pointers ...", I WANT circular
references even if it's a slow algorithm.

Thank for your help,
Lopet'
