Lots of people still run slower machines, and there are lots of
fairly intensive shell scripts in NetBSD, such as /etc/rc et al.

Try booting a 4MB 386/16MHz to full multi-user mode some day!  ;-)

You have to start somewhere and when some simple loop like this
identifies really interesting differences in performance with different
interpreter implementations, then you may already have made a really
