dp also stated this at one point on IRC. I didn't have time to discuss 
it at that point, but I think it ought to be discussed. Why does nevow 
need/want its own components API, that is either 1) is a fork that is 
nearly identical to the old twisted API (when running on Tw 1.3), or 2) 
uses the old twisted API compatibility layer (when running on Tw 2.0). 
Twisted has successfully disposed of its components API, for several 
good reasons. What purpose does it serve to continue the life of that 
code in Nevow?

As far as I'm concerned, the appropriate course of action is to convert 
everything to use the zope interface API.

Now not only are we keeping the old code, but heavily rewriting it? I 
have my doubts about those speed benefits, too...
