The numbers between f193883fc~1 and HEAD+patch are close to each
other.  It does not seem to make the whole difference with 15.3, but
most of it.  The difference can also be explained with some noise,
based on the number patterns of the third runs?

I have now applied the revert, ready for beta1.  Thanks for the
feedback!
