* Update the old speed calculator and associated profile data points to
      use a non-tiered moving average of the tunnel test time, avoiding the
      freshness issues of the old tiered speed stats.
    * Explicitly synchronize all of the methods on the PRNG, rather than just
      the feeder methods (sun and kaffe only need the feeder, but it seems ibm
      needs all of them synchronized).
    * Properly use the tunnel tests as part of the profile stats.
    * Don't flood the jobqueue with sequential persist profile tasks, but
      instead, inject a brief scheduling delay between them.
    * Reduce the TCP connection establishment timeout to 20s (which is still
      absurdly excessive)
    * Reduced the max resend delay to 30s so we can get some resends in when
      dealing with client apps that hang up early (e.g. wget)
    * Added more alternative socketManager factories (good call aum!)
