[Ruby] Memory profiling with Rails

[Scott Laird]

One of the big things looming on the Typo Development Horizon is
reducing our memory footprint.  Even after closing all of the known
leaks, Typo is still growing too big--I've seen 60 MB dispatchers
after a couple days' use.

Does anyone have any suggestions on how to best profile memory use
within Rails?  I'm planning on using something like this:

  http://raggle.org/pipermail/raggle-dev/2003-August/000086.html

But I'd love to discover that someone has a better tool for Ruby
memory tracking.  Even if it requires patching Ruby itself or
something similarly difficult.
