Where did all my memory go?

Well, I would assume, by having a better idea about how memory 
allocations work, and how they can be tracked, people could hint me as 
to how to figure out what's eating all the memory (since the top command 
isn't helping). Maybe three's a command I don't know about, or /proc 
statistics that could explain what's happening. If I knew how to debug 
the problem I wouldn't be asking the question, would I?

I guess I should cc Steve Grubb on this, since the kernel does include 
lspp patches.
