o Major bugfixes (circuit prediction): - Fix circuit prediction logic so that a client doesn't treat a stream as being "handled" by a circuit if that circuit already has isolation settings on it that might make it incompatible with the stream. This change should make Tor clients more responsive by improving their chances of having a pre-created circuit ready for use when a new client request arrives. Fixes bug 18859; bugfix on 0.2.3.3-alpha.
