A weak-reference (whichever kind is needed - I don't recall details) would
solve the problem and be subclass safe, but would involve even more overhead
that a finalizer. Keeping a notStartedCount is trivial, but keeping a set of
references requires array management etc. I don't think it is worth it.

BTW in discussing with other JSR-166 members the consensus is that the
ThreadGroup methods should be specified in terms of the new ThreadState
enum.
