Another change that has turned into something much bigger. This cleanup is
worth doing. Possible steps are (not in order and not in one push):
1. It seems like FinalizerObject should be removed in favor of classes that
implement interface Finalizable and are forced to implement finalizeAtExit, so
the Finalize thread can call the function on all the objects that get
registered to it. Not sure if this mechanism is useful or not. Maybe it
should be removed. If the process exits, are these connections closed?
2. If this mechanism is needed, rename Finalizer, FinalizerThread and
Finalizable (ugh) to TestCleaner{Thread}. Cleanable with cleanAtExit, and
rewrite/remove all references to these in the comments. Or just delete this
(better?)
3. Fix remaining comments and especially all the typos.
4. This patch removes the classes that have registered finalize methods in
favor of the cleaner mechanism, which looks good to me. These appear to be
cases where some connection needs to be closed, or something like that.
It seems to me that step 1 should be done then 4 as in this patch, leaving 2
and 3 to further cleanups and RFEs. Looks like we've uncovered a mess. The
purpose of these changes are to remove the dependence on finalizer() with their
associated warnings.
