And while you're at it, notice that cache is _added_ to "free" (ie,
brk(2)-able) space, because it's "user-used" but will automatically be
transferred to a process that requests it, while "buffers" is
_subtracted_ from "free" because although it's not user-used, it is
kernel-used, and therefore not available for brk(2)-ing.

And if you understood that, Arthur Andersen, Enron, and KPMG, not to
mention the IRS, could use your services as an accountant.  ;-)
