    Rx: raise rx_minPeerTimeout to 20ms
    
    At 2ms it is possible for the packet we are sending to be resent
    just about immediately as the retryTime computation occurs before
    the send takes place and not afterwards.  If the network send blocks,
    the retryTime may have already expired.
    
    We do not want rx_minPeerTimeout to be too large though because the
    value will end up being used as the backoff time period when the
    actual RTT for the connection is less than the rx_minPeerTimeout
    value.  Extensive testing shows 20ms to be an adequate compromise
    that avoids the vast majority of unnecessary resends without
    unnecessarily slowing down the connection if a packet is in fact
    lost.
