Thanks Martin. Yes that's what's confusing me when I run top or other 
tools and sort by memory usage. Even the big boys don't seem to be using 
*that* much.

xfce4-mixer is definitely in the frame as a suspect, it's just tricky 
trying to devise a testing strategy that doesn't involve switching 
something on or off then waiting for a a few hours to see if the swap 
usage changes! The trouble is, whenever I think I've found a likely 
candidate, and google it along with 'memory leak', practically 
everything seems to have some form when it comes to memory leaks.
