Of course, this whole problem would have gone away years ago, had more
folks implemented RFC6013. Or prior recommendations going back 15+ years.
Meanwhile, my experience with the Linux kernel team is that about 1/2 of
the tweak will go in, and the rest will fall by the wayside. Only about
1/3 of RFC6013 made it into 2.6.32, even though I started feeding them
code 6 months before publication.
