    the above is practical, very interesting and useful for 
me. it does not explain the algorithms of swapping, but it 
specifically recommends certain programs and provides 
references.

Great tip re PAE kernel! thanks! 

Questions remain: does RH recommend an upper limit of 
2GB for any swap partition? does RH recommend a total 
swap space of RAM + 2GB? Note the question is about 
RH recommendations, not the truth of swap: 
X="Red Hat" 
echo "what is Y? " 
read Y 
echo "a matter of curiosity; 1GB seems to work fine."
