 Replying to [comment:12 mikeperry]:
 > Ugh, the other wrinkle to check is if the hidden service comes back
 online after the socks timeout, but while that old intro circuit is still
 laying around. Does Tor try to reuse the intro in that case? Does that
 work, or does it break?

 First, no the `SocksTimeout` does *not* make the intro point circuit to
 close.

 I haven't tested it but I'm pretty sure the client won't find that circuit
 because it is set to `INTRODUCING` purpose where the SOCKS request makes
 the client look for an `INTRODUCE_ACK_WAIT` and if can't find any launches
 a new circuit and sets it to `INTRODUCING`.

 I need to confirm that but I do think we'll lose track of this circuit
 until its idle timeout of 52 minutes hehe.
