 > Before I review this one, I'd like to hear from the TBB team about
 whether this general approach meets their needs.  I don't think I've seen
 an answer there.  ''I'm'' happy with an events-based approach, but the
 whole point of this ticket is to improve TBB usability, so I'd like to
 know whether we're actually going to do that before we merge.

 To summarize: I'm working on #5752 (isolate streams by URL bar domain) and
 descendants. I have implemented a patch for #3455, where the browser is
 using a unique SOCKS username and password (u+p) for each URL bar domain,
 and tor accordingly sets up a separate circuit for each unique u+p. The
 next step (#8641) is to implement a UI, attached to the browser's URL bar,
 that shows the progress of a circuit as it's being built, and the exit IP
 of that circuit. So we need to be able to query/monitor tor for the
 circuit ID corresponding to the u+p.

 At this point, I don't expect to need any isolation flags apart from SOCKS
 u+p. So we could remove the other isolation flag stuff from the patch.
 But, given the work Robert was doing, I imagined you might want all
 isolation flags covered, for the sake of completeness. I'd be glad to hear
 your opinion either way.

 In the meantime I can start working with the TBB team on a design and
 prototype for the #8641 UI, which may help solidify exactly what we need
 in the patch for this ticket. Any suggestions are much appreciated!
