commit b5d13d11c90cb94193b6071e8c525f75cc77b861 Author: Nick Mathewson <nickm@torproject.org> Date: Sat Dec 21 10:15:09 2013 -0500 Fix a logic error in circuit_stream_is_being_handled. When I introduced the unusable_for_new_circuits flag in 62fb209d837f3f551, I had a spurious ! in the circuit_stream_is_being_handled loop. This made us decide that non-unusable circuits (that is, usable ones) were the ones to avoid, and caused it to launch a bunch of extra circuits.
