> After some more discussion happened, let's try to fix that on the
browser side (first). mcs/brade: can you look into it?
Yes, we can take a look. It would be helpful to develop a better
understanding of what kind of attack(s) we are trying to prevent. That
might lead to a better design. For example, do we want to limit the rate
at which new circuits can be opened or do we just want to refuse to open
more than N circuits per site? Unfortunately, Kathy and I don't really
know enough about `tor` and the Tor Network to do that kind of analysis,
so hints about what should be done would be greatly appreciated.
