If you can, take a look at smem (http://www.selenic.com/smem/) to see how
much memory these procs are _really_ using.
This tool looks at how much memory is shared between procs and gives you a
much better sense of how much memory it costs _per process_.
But you need to be on a relatively recent Linux kernel to use it.
