Try
   http://rubyforge.org/snippet/detail.php?type=snippet&id=70

It is really _very_ trivial to use. (it is also pretty brute force and 
dumb code)

Save to snippet as MemoryProfile.rb and then run your code as

ruby -w -r MemoryProfile your_code.rb

On exit it reports simple counts and also traverses the object tree to
give detailed counts of what object is using what and prints the
largest object as well. The log file is appended to /tmp/memory_profile.log

It takes quite a lot of time and memory...

It also dumps /proc/pid/status to display your vm usage, so it is a
little Linux specific, but you can cure that with a  # or two.

Refactorers do it a little better every time.
