I'm sorry for a noise. (maybe we can use tera-bytes in 64bit land.)

BTW, Redhat's RHEL instlation guide says

M=memory size
S=swap size

If M < 2G
   S = M * 2
   S = M + 2

as recomended value (for RHEL5). And maybe other guides will say the same
kind of....

Maybe we can  have enough swap space in usual case. Hmm.
