Comment (by arma):

 Two more thoughts:

 (F) Are you sure that the proposed branch is related to the topic of this
 ticket? The ticket title and body seem quite different from what the
 branch does. That makes me wonder if maybe we're not actually solving the
 original bug report. :)

 (G) Do we have a handle on how often existing guards respond with reason
 resource-limit? Imagine a Tor client that makes a bunch of circuits often,
 say because it's an active onion service. And let's say on average 5% of
 create cells get a resource-limit response. And let's say we wait 30
 minutes before retrying guard that we marked as down. We're going to churn
 through a *lot* of guards this way, right?
