Most likely Garbage Collection is not being run for your (rather short) 
script.  Does your message print when you run GC.start()? If so your 
message is working fine.  Try writing something that creates a log of 
garbage to be collected. I think something like:

i=1
while (true)
   puts "message #{i}"
   i+=1
end

should do the trick.  Of course, that particular program will never exit.
