<http://codepad.org/> is a pastebin-like website that lets people upload
code in a dozen different languages, and it runs it. They have info up
about how it's secure at <http://codepad.org/about>.

I'm pretty sure there's another similar website that's specific to
Python, but I can't remember it. Anyway, it was similar, using virtual
machines, a firewall, and killing stuff that ran for longer than 20
seconds, IIRC.

(Thanks for the link to codepad, habnabit.)
