Comment (by robgjansen):

 Yeah, you're right, I wasn't very clear. I was trying to suggest something
 similar to a timestamp per cell like we have with circuit queues. How
 about we keep a timestamp queue on the streams. We append a timestamp for
 every N bytes written from the circuit to the edge buffer, and then pop
 the head of the timestamp queue after we flush N bytes. Will this allow us
 to track how long every N byte chunk has been waiting in the buffer?
