Comment:

 Don't we get the isolation we need for free with our current
 implementation of "Use different circuits for different URL bar domains"?

 I made a quick test with loading google.com and
 https://people.torproject.org/~gk/misc/keep-alive.html (which loads a
 resource requested as well if one loads google.com) making sure I did that
 within our current keep-alive limit and all requests are properly isolated
 meaning they use different circuits. How should the keep-alive you get
 while loading google.com interfere with the one you get if loading keep-
 alive.html provided they use different exit nodes?

 Recalling the discussion on IRC with s7r I think that would even mitigate
 the problem of onion sites loading foo.com clearnet resources while having
 foo.com open in a different tab.

 What am I missing?
