Comment:

 An upper limit on the circuit queue bound with the SENDME logic would look
 like this: `bug25226_033_01`

 The gist is that if the queue size goes above the circuit window start
 maximum limit (1000), the circuit is closed with TORPROTOCOL reason.
 Assuming we ever reach that limit, it means something is wrong in the path
 and the edge connection keeps sending stuff even though it shouldn't.
