Keeping Ticket Statistics

[mulhern_at_yocto]

This is really about Twisted again, but it would be neat if it were possible to keep statistics about the number of revisions between the first patch and the final application. One could look them up and see how one was doing with respect to others, over time, etc. Of course, as time went by, one's patches would become more ambitious, and so the issues that might come up in a review would perhaps be more interesting, and so forth.
