Comment:

 Thanks neel! I realized that we actually need to not return any intro
 point if it is not usable right in `rend_client_get_random_intro_impl()`
 which is where it checks as well for the IP timing out.

 I've taken the branch over based on your work so to get it a bit fast
 tracked into upstream :).

 Branch: `ticket25568_043_01`
 PR: https://github.com/torproject/tor/pull/1484

 I think NO backport here because HSv2 and minor reachability issue. If we
 don't want that, I can provide an 035 branch then.
