Hello.
Instead of patch-2.txt and patch-3.txt, the following more simple patch
would also fix the issue (I've tested it on single-cpu systems and also
on m6a.large instances from AWS, which have 1 core and two threads).
(Suggested by Drew Parsons in Bug#1071722, which is similar to this one).
(IMO the patch called patch-1.txt which I posted before should still be
applied because it removes unnecessary complexity).
Thanks.
