P.S. I'm curious about the strange seemingly unneeded code fragments in 
FinalizerThread and both Runnables. For example:

169         forkSecondaryFinalizer(new Runnable() {
170*private volatile boolean running;*
171             public void run() {
172*if (running)*
173*return;*
174*running = true;*

The FinalizerThread and each Runnable instance is only executed once. Why these 
checks then? Does anybody know?

I was wondering that too. A Thread is an instance of Runnable. So a finalize 
method could re-exec the current finalizer thread on another another thread.

Right. I added these a while back to ensure that this does not happen.
