Thanks a lot for the various clarifications above, where essentially turns out
that some details of my patch are correct essentially by chance ;) Seriously,
I'm thinking the following: since 8 is getting real close, what if, for 8, for
the known mild regressions, we go ahead with my super safe Plan B which I
mentioned at beginning of the thread, then as soon as trunk branches we
immediately apply my patch and we give it a serious spin, say we rebuild
distros with it, and see what happens?
