Virtual Memory sub-TODO:
* Check if the page selection algorithm is working well.
* Check if the page selection algorithm is working well
* Divide swappability of objects by refcount
* vm-swap-file <filename>. The swap file should go where the user wants, and if it's already there and of the right size we can avoid to create it again.
* it should be possible to give the vm-max-memory option in megabyte, gigabyte, ..., just using 2GB, 100MB, and so forth.
* redis-cli vmstat, calling INFO every second and printing VM stats ala vmstat.
* protect zmalloc memory usage increments with a mutex
* Try to understand what can be moved into I/O threads that currently is instead handled by the main thread. For instance swapping file table scannig to find contiguous page could be a potential candidate (but I'm not convinced it's a good idea, better to improve the algorithm, for instance double the fast forward at every step?).
