Comment (by andrea):

 Actually, there's another bug here: there exist a few circumstances where
 a circuit is not attached to its channel's mux but still has n_chan/p_chan
 set.  Specifically, if the circuit is marked for close (see the
 circuitmux_detach_circuit() calls in circuit_mark_for_close_() which was
 the case I just observed this for), and briefly during
 circuit_set_circid_chan_helper() (but I don't think there's any way for
 this to be called in that interval).
