I did not understand you did that. Although this was almost one year
ago, I remember being unable to understand how your code really worked
and why it was done that way. Maybe the "architectural" problems I saw
there at that time were merely related to my inability to figure out how
the code worked.

I am trying to lazily evaluate the end of transmission events and

I'll talk to hossein and will try to figure out how to best send you
this code on tuesday
