actually... we DID do fragmentation in one of the messages. but i think that one didn't do windowing or something. this is the problem of using UDP, everyone thinks they're Van Jacobson and re-invents TCP poorly. In the case of the viewer, we had at least three implementations of "random transport over UDP," each talking with a different part of the back-end. Each used the same algorithm to deal with packet loss, however: dump core and wait five minutes. (I jest. I think we mostly fixed that, but it did happen occasionally.)
