Do you need to lock things down via mlock/mlockall/memcntl
before using meminfo, otherwise the answers could be changing behind your
back if mappings are invalidated for some reason (like pageout).
Strictly speaking, yes... but as long as you're using the memory and
the machine has enough, you're likely to be ok....
