I've always preferred to describe what's going on by saying that the VM
implicitly maintains a weak reference to all objects and that the gc
collects objects that are only weakly referenced.  From this perspective,
objects are never ressurrected, but rather allInstances creates a strong
reference that will prevent the object from being gc'd.

Out of curiosity: what happens in the current VM with objects without
references to them which are not yet garbage collected when allInstances is
sent to their respective classes ? Are such objects resurrected ?
