Well I accept that you need some unlocked pages to keep things running,
however hardcoding the limit to 1/3 is a bit extreme. I thought this
was the whole point of sysctl/rlimit settings, i.e. I'm running as
root, I know what I'm doing, if I want to lock 95% of physical memory,
then let me do it.
Anyway, thanks for demystifying the issue.
