For anyone who's curious, you _can_ do it by using fcntl's file locking
before making any changes to your shared memory region, but this means
you only get one lock per file. So if you've got one variable, just lock
the file you're mmaping. If you've got dozens, you're going to need a
lot of lockfiles.
