No, the correction followed upon his accurate report of a regression, 
last August, which was unfortunately mixed in with grumbles and 
inaccurate claims. Others separated out and verified the accurate 
report. I reported it to pydev and enquired as to its necessity, I 
believe Mark opened the tracker issue, and the two people who worked on 
optimizing 3.3 a year ago fairly quickly came up with two different 
patches. The several month delay after was a matter of testing and 
picking the best approach.
