OK, thanks for the precision.

So maybe in the end we should just merge d11a4dc18 that Ben found to be
the least invasive one fixing the issues, and we'd be in sync with the
rest of the stable branches, even if, as you noted a few days ago, it's
only a partial fix for the issue.

Ben, what's your opinion on this ? I know it's never fun to do backports
and not merge them later, but I trust David more than anyone else on the
network part, so if he decided that while incomplete, the patch above
was all that was needed for other stable branches, maybe we should just
stay on the safe side and do the same ?

Willy
