> If mlockall() is called while allocated VA space is bigger than
> amount of available RAM, FreeBSD kernel will deadlock and need
> a hard reboot. We do allocate big amounts of memory because of
> how new memory subsystem works, so calling mlockall() will cause
> a deadlock. So, disable mlockall() by default on FreeBSD.
