Comment:

 Agreed; my best guess for explanation here would be that on some relay-to-
 relay connection, you're getting close to the the limit of 2^15^  circuit
 IDs in each direction that Tor 0.2.3 and earlier had.

 We should never be calling this function on a connection with a client,
 since we should never be trying to extend a circuit towards a client.

 Also I bet this is a very expensive check if we're really exhausting the
 circID space here.  So, upgrading this to "major" and marking
 024-backportable.
