Right -- my first question would be "8 circuits per what?" That is,
how often does it use eight new circuits?

If it makes 8 circuits and then holds them open and uses each of them
for a long period of time, that sounds like a solid win -- you get
isolation between streams with little downside.

If we're talking 8 circuits per new gadget, and the new gadgets are
pretty frequent, then the tradeoff becomes more complicated.
