> This hashCode is implemented based on #states and #transitions.
> These methods use getNumberedStates() though, which may oversize itself
> during construction and then "size down" when its done. But numberedStates is
> prematurely set (before its "ready"), which can cause a hashCode call from
> another thread to see a corrupt state... causing things like NPEs from null
> states and other strangeness. I don't think we should set this variable until
> its "finished".
