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.
