No! Never run important finalization in a class destructor! The

I always thought that the moment of finalization is undetermined,
but that the GC does indeed run the destructor... Weird, I'll
have to look into that. After all what would be the point of
destructors if they are not guaranteed to be run?
Still, if you are to manually call a cleanup method, you might as
well call destroy on the instance to force the destructor to run
right away, right? Not that it makes any difference to call
instance.cleanup() or destroy(instance) so long as cleanup and
the destructor contain the same code.
