Seems to me like you should set the size of the swap partition to 
whatever you need in virtual memory.

Except to make sure that you have enough space in the g partition for /usr,
it seems kind of silly to restrict swap space or waste disk space by having
more than one needs just to follow some rule-of-thumb for sizing.
