That sounds extremely non-likely as it would imply the kernel fails to
honor a successful mlockall(), unless other processes on the same
machine are being swapped out. Did the process really have permission
to do the mlockall()?

(Not that I disagree in any way that swap should be disabled, +1 on that.)
