If the cleaning action is run from the Cleaner machinery, then the ZipFile is claimed by GC so no memory is being held on to. If the cleaning action is run from `ZipFile.close()`, then the ZipFile is no longer "usable" and client code should have no good reason to maintain references to the ZipFile.

That said, sure, we can trim the ArrayList to remove any large Object[] for the elements.
