I wonder would adapting LongLivedPorts to enforce circuit isolation achieve
this requirement without the risk of inducing exponential circuit creation.
Since applications that use LongLivedPorts by definition require long-
running connections and create new connections relatively infrequently it
seems like a good fit.
Changing LongLivedPorts this way would all the problem-cases I can remember
that gave rise to this proposal, most of which involved mixing chat/ssh/irc
with browsing and the like.
