Perl applies a mark-and-sweep alternate GC in some occasions (when a thread dies, I think) in order to reclaim circular references. Note that the "every value is a string" Perl stanza makes it difficult to create true circular references; this is feasible, but "normal" Perl code does not, which is why reference counting works well with Perl.
