OK, i downloaded and installed ruby1.7.3, and... it's faster
than older versions of ruby, but still there's a large distance
beetwen speeds of python and ruby (py is faster).
A little test: ruby1.7.3, blah = open('/etc/termcap-BSD', 'r').readlines

% time ruby rb.rb
ruby rb.rb  0.40s user 0.09s system 97% cpu 0.500 total

ps. for speed maniacs (not me;)): it's time to switch to ruby1.7.3
