Thanks. I thought they were garbage collected in order by tag in 4.0.1, but
I couldn't remember for sure.

Regardless, I wouldn't feel comfortable counting on the order of deletion
because it might change in some future version. This is a much-debated
theme about finalisation methods and the usual suggestion is that safe
coding requires making as few assumptions as possible. That is what I was
trying to communicate.

Rici.
