I suppose if anything can be done with existing facilities, they should be
utilised. I don't take it much if some name is misleading. We have a lot of
much more severe issues and live with them. -1 for "just add"

> This patch adds a {{prepare}} and a {{finish}} method to the interface of
> {{DocTransformer}} allowing a developer to perform actions before/after a doc
> transformer is applied to a result set. My use case was to benchmark the
> performance of a transformer, since transformer time is not part of
> {{QTime}}.
