Not precisely It's probably because they always need to be traversed by the GC, even if they aren't live [14:13] They get collected the second time they would get copied, if the last time they got copied only due to the fact they have a finalizer So you end up copying them once too often Hm. Not sure I follow. You’re talking about the finalizers being copied? And if they aren’t live, why would they be traversed? [14:15] The objects that have the finalizer They might not be live, but the finalizer needs to operate on the object, so the object needs to be kept alive one more round of GC
