ipfw uses /etc/services if you use, e.g., "domain" instead of "53" in
your rules.  I would hope any application that seriously used
/etc/services would read it once, store it in some speedily accessible
form, and work from there.  As a flat, human-created file, /etc/services
would not be my candidate for efficient program access.
