Do you have any evidence that there is anybody else besides Mike who has this
Also, I usually try to "sort out" things after there is a clear understanding of
what the problem is and how it should be fixed.

I do not see any problem with the code*.* I do not see any explanation of the
root cause of the problem that Mike has. I do not see why anything has to be
reverted. Especially because "since we're so close to 9.2-REL".
Just in case, I'll remind that the commit in question is in stable/9 since Dec
