I looked at the latest version (thanks, Tom, for this effort!) and
stumbled over:

Each tab is its own Tor circuit

Is this due to the 100-Foot overview nature (maybe it looks that way
from 100 feet above :) )? The thing is that not the tab is the important
isolation criterion but the base domain of the URL you have in your
location bar. Thus, requests to blog.torproject.org and
trac.torproject.org in different tabs go over the same circuit (let's
ignore some corner cases like circuit timeouts etc.). And then there is
the catch-all circuit for requests not associated with a window/tab at
all... and all the things we have not fixed yet. Oh well...
