--- Comment #7 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note the kernel has many of these locks too.  Have you reported those cases to
them?

And yes I know about the number of cores increasing, trust me, I use a 96 (or
48 depending on if I am on single socket or two) core machines for most of my
work now so I know all about this issue.  Plus I will be using a 104 core
machine soon too (2x54).  I have been looking into lock issues too.
