ovs-vswitchd: Call mlockall() from the daemon, not the parent or monitor.
mlockall(2) says:
Memory locks are not inherited by a child created via fork(2) and are
automatically removed (unlocked) during an execve(2) or when the
process terminates.
which means that --mlockall was ineffective in combination with --detach
or --monitor or both. Both are used in the most common production
configuration of Open vSwitch, so this means that --mlockall has never been
effective in production.
