1.123.11 Object: finalization

addToBeFinalized

Arrange things so that #finalize is sent to the object when the garbage collector finds out there are only weak references to it.

finalize

Do nothing by default

mourn

This method is sent by the VM to weak and ephemeron objects when one of their fields is found out to be garbage collectable (this means, for weak objects, that there are no references to it from non-weak objects, and for ephemeron objects, that the only paths to the first instance variable pass through other instance variables of the same ephemeron). The default behavior is to do nothing.

removeToBeFinalized

Unregister the object, so that #finalize is no longer sent to the object when the garbage collector finds out there are only weak references to it.
