I have 4 GB of RAM, and am barely running anything, but I still have cold 
processes swapped out.  When they redid virtual memory a few kernel versions 
ago, it seems to always insist on using some swap for processes that have 
been idle for some prescribed time.  I'm not on LKML, and not a kernel guru, 
and could be talking right out my butt here, but I went through some kind of 
attempt to eliminate swap some time back (a year or two ago, maybe?) and the 
only way to eliminate swap was to eliminate swap.  If you don't have any swap 
partitions or swapfiles, then, and IIRC only then, will you run swap-free, no 
matter how much RAM you have.

But I could be talking right out my butt.  I'm barely even awake yet, and on 
my way out the door to work.
