I'm unhappy about the caveat "if the finalizer make invoke synchronization
on the object."

I understand that the motivation is to maximise the possibilities of
removing redundant synchronization, but the caveat impinges on reachability
for the purposes of the reference classes WeakReference, etc.

I've raises the issue of these classes in the context of finalization
discussions before, but my comments have been systematically ignored.

It might be felt that his matter is outside the scope of a new Java memory
model, but I'm not really sure how finalization got in either.
