Sloth loves Chunk, and we love Sloth for Mac
It's nice to know what's sucking up all of your memory (pr0n) and what's bogging down your processor (DVD burning).
Sloth for Mac OS X shows us exactly what's running, Windows style.
You can see which application is running which process, reveal the directory it's running out of, and kill it off if you want. If you're super geeky and/or bored you can even look at the IP and Unix sockets to see what application is connecting to the interwebs at any given time.
This is a really handy dandy tool, and the source is available too for monkeying...er, slothing around.
One of the better parts about Sloth is that it's a Cocoa app, and runs nice and slick on your Mac.
