It sounds like this might be a bug in the version of ruby you have, 
because it doesn't explode in memory usage when I run it here either. 
Running the exact script above, RedHat 7.1, Ruby 1.7.0 (CVS), gives:

(And so on, til the end of time...) -- memory usage never grows.

What version of Ruby are you using? I'm using (and possibly ts is 
too--I didn't see what version he said) a copy compiled from CVS, so 
it's possible that the version you have really does have a bug.
