This consumption is quite static (it only changes between swapon/swapoff
switches). The resulting value can be calculated as a linear combination
of entries in /proc/swaps already (if you know the right coefficients).

I'm not sure this warrants the new entry (or is my assumption about
static-ness wrong?)
