Document auditing setups for testers to use
We've got a TBB AppArmor profile at https://trac.torproject.org/projects/tor/wiki/doc/AppArmorForTBB. On legacy/trac#5741 (closed), some dude named unknown posted iptables rules that log violations. I hear there is also an OSX Seatbelt policy floating around somewhere that may also be useful.
We should create a meta document, or perhaps just describe on https://trac.torproject.org/projects/tor/wiki/doc/build/BuildSignoff how to use these things to test for disk leaks, proxy issues, oddities, and other violations.
