Subject: MRI GC never collects?

With the following code:

def finalized_puts bad, benign
    ObjectSpace.define_finalizer(bad) { puts benign.to_s }
end

n = 0
loop {
  a = [3]
  finalized_puts a, n
#  GC.start
  n += 1
  if n % 10000 == 0
    print '.'
  end
}


I'd "expect" that every so often it spits out some numbers, as objects
are collected (jruby does do it this way).

However with both
ruby 1.9.2p180 (2011-02-18) [i386-mingw32]
and
ruby 1.8.7 (2011-02-18 patchlevel 334) [i386-mingw32]

That code appears to just eat memory forever, and never run the
finalizers.

Am I missing anything here? Is it reproducible for y'all?
