* Divide swappability of objects by refcount
* Use multiple open FDs against the VM file, one for thread.
* EXISTS should avoid loading the object if possible without making the code too specialized.
* vm-min-age <seconds> option
* Make sure objects loaded from the VM are specially encoded when possible.
