I haven't made a survey of all of the functions yet but
fucntions return -ENORESTARTNOHAND will never return -EINTR and are
immune from this problem.

AKA pselect is fine.  While epoll_pwait can be affected.

Has anyone contacted Omar Kilani to see if that is his issue?

So far the only regression report I am seeing is from Eric Wong.

Are there any others?  How did we get to be talking about more
than just epoll_pwait?
