How do you Open a "Task Manager" (as in Chrome) in Safari?

I assumed that since both browsers are based on WebKit, that this feature would crossover, or whatnot... I guess I'm wondering if any of the Google Chrome "nerd" stuff, especially the "task manager" is available for Safari.. either natively, or via extensions??

WebKit is just the rendering engine - you could use Activity Viewer or top to see Safari's activity.

IIRC though Chrome renders every window/tab as its own process; Safari does sandbox plug-ins but not individual pages.

In Activity Monitor, you can mouse over the safari tasks and it will pop-up which URLs are on that task.
