The problem with exposing internal methods as protected is that it
really limits our ability to change how classes are implemented in the
future.  If it was there as protected in 1.0 then that method would have
to stick around forever with exactly the same semantics.  I think that's
more than we should promise, don't you?  We've done it in other places,
but I think it's a problem.
