 I agree that's a bad property because it allows a web adversary to cause
 your browser to keep making new circuits until you pick one that uses its
 middle node.

 content elements of a given URL bar, so that at least content elements
 don't get to cause you to create tons of circuits. Once a circuit can load
 a top-level url correctly, it should be considered reliable enough not to
 abandon if a DNS or other stream times out. This might actually require a
 new Tor child ticket and patch, though...

 Not that I am aware of. I've opened a new ticket: #13669
