Leo has been working on this for his Version 4.  Thus I see no reason for me
to spend time on it now 8-).  From the alpha code that he sent me, he has
three different ways of thresholding.  They all work after the trees are
grown, so the OOB estimates do not reflect the threshold.  I don't see a
good way to deal with that so far.
