I think that the whole "class revision number" hack is not needed any more.  

At some point "factories" used to be some strange and complicated notion, but 
this has been quite simplified.  Nowaways, for example, instance creation 
points are just recorded somewhere associated with the class, and it's easy 
enough to reflow from there whenever the classdef changes.

We should get rid of rev numbers; it would remove all the problems we keep
having with it.  Instead we can simply record all the 'getattr' operations,
i.e. record where each class attribute is read.  That's both easy to do now
and considerably more efficient (when a specific attribute is generalized it
would only reflow from the places that really use it).
