 From what I gather from man swapon, the priority is a value between 0 
and 32767, but which field in the /etc/fstab is the "options" field? 

/dev/hda5   swap   swap   defaults   0 0
LABEL=SWAP-hdb7   swap   swap   defaults   0 0

Which one do you add the pri=0 to set the swappiness ?

OTOH, if you turn swap completely off and the system needs more memory 
than is available, I would assume a kernel panic would ensue at that 
point, or something would die.  Just guessing on that part.
