Well do you understand the concern? Have you done debugging in
this kind of environment? I have!

A bug that damages the integrity of the collection mechanism can
often take many garbage collection cycles to make itself known,
spreading like a kind of cancer at each garbage collection
cycle. Furthermore, the result might just be a subtle memory
leak, particularly hard to detect, when the real reason for the
problem has been disposed of many GC cycles ago.
