Sorry, but I don't understand exactly what do you mean. This class is pretty much internal to Rails. The documentation is only for people that wishes to implement their own file updater. In other words, this implementation is internal to Rails, but the contract used by the reloader should be stable from 3.2 on. Maybe we should add such a note to this class docs?
