Try setting sysctl vm.swappiness=0 (for permanent add it /etc/sysctl.conf 
and then sysctl -p).
It should instruct linux to (try) not to use swap at all.

p.s. I'm running my varnish boxes without swap at all - the 
behaviour/performance is much more predictable that way (you can test how it 
works out for you with 'swapoff -a')
