Well, even though the reverted patch is clumsy and takes the wrong
direction, it actually does the job and fixes the issue at hand.

When reverting in stable patch #3 of this series (which fixes the issue
in a better way) must be cherry-picked into stable too, otherwise we'll
get a regression.

I'd tend to not revert this one in stable though.
