Patch: thread finalization

[Tom Tromey]

I'm committing this patch.  It arranges for dead threads to be removed
from their containing ThreadGroup.  This allows the thread to be
collected, and thus finalized.

	* java/lang/ThreadGroup.java: Fixed now-erroneous comment.
	* java/lang/natThread.cc (finish_): Call ThreadGroup.remove.
