 There are classes of relay cells that don't count in the circuit windows.
 Specifically, only data relay cells count in the circuit windows.

 So for example, a malicious website could arrange for the client to open
 2200 streams to it, and then the website could close them all at once.
 2200 relay end cells would work their way back towards the client. The
 #9063 fix would get upset and kill the circuit.
