I have to agree w/Randy that the SBUs are a rough approximation and
usefull as such. I use a 3rd method by timing configure-make-make
install using &&s for processes that usually take 3~5 SBUs and divided
by the number in the book to get the value of 1 SBU. Then, when I see 11
SBUs, I know if have time to have a full meail or just a sandwich for
