 Yes.  I opened one stream to an IRC hidden service, sent `SIGNAL NEWNYM`
 to the control port, and then opened another stream to the same hidden
 service; I read the control-port event logs produced by `SETEVENTS SIGNAL
 STREAM CIRC` carefully, and then verified that I had two circuits open to
 the same hidden service using `GETINFO circuit-status`.

 I also performed the same test without this patch, and that version of Tor
 sent the stream opened after `NEWNYM` over the previously existing
 rendezvous circuit (and did not build a second rendezvous circuit).
