I think you have a misunderstanding as to what swap is for - it's not 
for memory-hungry applications.  Swap is not a replacement for memory. 
It's good in cases where you have a lot of applications and many of them 
are idle and you can afford the swapin/swapout.  Swap is a very bad 
substitute for memory-hungry applications.  You need to buy more memory.
