Okay, but I think we need some way to retrofit existing classes in a
fairly uniform manner.

The Closable approach doesn't really fly.  You probably want
Process#destroy(), Timer#cancel(), ExecutorService#shutdown(), and
some more.  Looking for classes which implement finalize() should
increase the length of the list.  Many of them will free native
resources, and doing as early as possible will increase overall system
robustness and determinism.
