I know what you mean, just that there are only very few CGI calls in 
pyblosxom, and that can easily be converted to twisted if I want.

Hmm, I'll look into reactor.callInThread() first, there's one part of 
pyblosxom core that does this for loop which can get slow if there are a 
large number of entries.

It does look wierd in the code when I do:

def render(self, request):
    request.write("hello world")
    request.finish()
    return NOT_DONE_YET

Is this what you are saying?

Hey, thanks for the help, twisted is really nice in this aspect. But one 
thing for sure, it's not easy for me to learn, but it's one of those 
things that if you know how to, then everything else seems easier :) I'm 
trying to learn more of twisted and see if it can be used for my project.
