as swap usage, 7th as total system swap, 8th as free swap and 9th as
memory usage with buffers and cache
* FreeBSD: see above, but 10th value as memory usage with buffers and cache
as percent and 11th value as wired memory (memory used by kernel) is
reported
* FreeBSD: see above, but 9th value is not returned (always `-1`) and there
is a 10th value giving wired memory
