Looking at the implementation of rend.Page.renderHTTP makes me suspect
that the way to do this is by making a beforeRender(self, request)
method. Is this right?

And if so, beforeRender looks like it's meant to be synchronous, and
unfortunately my "check for new data" method needs to wait on a Deferred
to be called back.
