This is not a question of fairness.  If patches have been accepted in
the past without benchmarking (pure bugfixes don't count for obvious
reasons), that is unfortunate.  Such oversights in the past must not
be used to justify continued sloppiness.

Quality comes as a result of strictness, not from fairness.

While I do consider Diego's cleanup efforts worthwhile, this particular
patch undoubtedly still has some questions unanswered.  Someone reported
a much greater slowdown than Diego measured, so this must be investigated
until we can find the cause.
