We added the wording to deal with complaints that pools were not
being auto-shutdown. But we didn't notice that the conditions for
finalization to trigger were the same as the conditions for
finalization not being necessary! (Just GCing would be fine.)
The best solution seems to be just to remove the method, and
adjust the javadoc wording to refer to GC vs finalization.
I think this would be binary compatible?
