[gclist] Finalization in the Boehm-Weiser-collector

[Thomas Weitzel]

I've noticed that when you associate objects with finalization functions in the
Boehm-Weiser collector, and more than one of those objects are members of a
cyclic graph, the whole cycle becomes uncollectable.

This is a bit unfortunate when one wants to use the collector with C++, because
it is common in the C++ community to use destructors for many other things
beside freeing
members.

What is the reason for this behaviour? Can it be changed?
