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?
