Are there any decent python memory profilers available?

I have a rather large python application (uses around 40MB of memory to
start) that gradually chews up memory over many hours. I've done a
little googling around, but it looks like I'm faced with prowling
through the gc.get_objects() myself. I need a tool to identify where
the memory is going. It might even be a leak in a DLL, so maybe a pure
python profiler isn't the best, although it would certainly help
localize the problem.
