OK for HEAD.

Just a nit - in the ChangeLog I wouldn't say 'Removes potential
slowdown'. This implies that something could be slower for the end user.
Just wanted to clarify that I didn't point this out for performance
reasons :) The performance gain here is virtually impossible to measure.

The main improvement here is simply, moving code that doesn't belong in
a loop. This helps readability and is a more logical design.
