Regrettably, few of the GUI installers for Linux (SuSE or Red Hat, for 
example), include adequate swap space in their "suggested" disk formatting.  
Some versions of some distributions do not create a swap partition at all; 
others allocate only 130mb to this partition regardless of actual RAM.

So regardless of what they *should* be doing, there's thousands of Linux users 
out there with too little or no swap on disk ...
