Just to bore everyone but Simon and me to tears, here is 'fair' timing2.sh
variant using an r version that does not autoload().
edd at ron:/tmp$ ./timing3.sh
--- our r calling summary() 20 times
--- GNU R's Rscript calling summary() 20 times
--- our (empty) r calling summary() 20 times
--- GNU R's (empty) Rscript calling summary() 20 times

It's back to where we were, but Simon's point on library() taking a good
chunk of time is acknowledge. I'll add a new switch to littler, which is
due for a new release anyway providing the new tempdir option that suggested
by Paul Gilbert a while back.
Three out of two people have difficulties with fractions.
