Looked at the same top info, and I don't understand what I see either. With processes running, I'm seeing close to 500mb of stuff swapped out, but according to free, only the 2.2 mb is swapped. There's gotta be more to this than meets the eye, or something is lying about the swap. The system monitor also shows only 2.2mb of swap in use, so where is top getting this 500+ mb of swap data from?
I suspect Kai and Les have hit on it. I first thought it sounded like a bug, now it may be only a "bug" in documentation not telling it like it is.

I'll tell you one theory I had earlier today. What if the summary line was reporting "pages" swapped? At 4K/page time 160,000 it cam awful close to matching the total of all the individual entries under the "SWAP" column. I had though I was onto something. If someone's on an arch with other than 4K page size, ...
It was tempting, yes it was. Fortunately, I decided to *ask* rather than *propose*. So I seem only half as much and idiot as I might have seemed (I hope)!
Both theories sound very plausible to me. But since I never heard of any userspace program using "pages" as a unit, I'm tending more toward the one Kai and Les proposed. Not entirely discarting yours, tho.
