Java finalizers are not called upon VM exit, only when object is swept
by GC (for example when the object is destroyed upon program exit), the
CPython docs read that this is the case for Python too. Is this
behaviour standard for all VM implementations or is
implementation-dependent (CPython, Jython, IronPython)?
