 Right now the client goes through the process of fetching the hidden
 service descriptor, and once it's there, then the client realizes it wants
 a rendezvous circuit ready. It could instead do these two steps in
 parallel.

 Now, the reason not to do it is that we can just cannibalize an available
 general-purpose circuit and we've nearly got a rendezvous point. And then
 Tor client will indeed already try to keep general-purpose circuits
 around. So maybe it is not worth the wasted circuit? I'm not sure.
