* Added a pool of PRNGs using a different synchronization technique,
      hopefully sufficient to work around IBM's PRNG bugs until we get our
      own Fortuna.
    * In the streaming lib, don't jack up the RTT on NACK, and have the window
      size bound the not-yet-ready messages to the peer, not the unacked
      message count (not sure yet whether this is worthwile).
    * Many additions to the messageHistory log.
    * Handle out of order tunnel fragment delivery (not an issue on the live
      net with TCP, but critical with UDP).
and for udp stuff:
* implemented tcp-esque rto code in the udp transport
* make sure we don't ACK too many messages at once
* transmit fragments in a simple (nonrandom) order so that we can more easily
  adjust timeouts/etc.
* let the active outbound pool grow dynamically if there are outbound slots to
  spare
* use a simple decaying bloom filter at the UDP level to drop duplicate resent
  packets.
