Yes and presumably to do your webmachine-a-like you'll be using the
internal dispatch like this anyway, right? But it would definitely be
better for use the internal dispatch logic. Also is there a straight
API call back into YAWS for serving a request, especially a file one
(so that sendfile will kick in if configured) ?

BTW thanks for the feedback, this has been very useful and I'm going
to start playing with YAWS properly now I think.
