Here it goes (Linux System Adm. Guide - Ch.5 Memory Management): 

It's a good idea to have at least some swap space, even if your 
calculations indicate that you need none. Linux uses swap space 
somewhat aggressively, so that as much physical memory as possible can 
be kept free. Linux will swap out memory pages that have not been used, 
even if the memory is not yet needed for anything. This avoids waiting 
for swapping when it is needed: the swapping can be done earlier, when 
the disk is otherwise idle.
