    Revises the algorithm governing the sending of link request messages
    to take into account the number of nodes each bearer is currently in
    contact with, and to ensure more rapid rediscovery of neighboring nodes
    if a bearer fails and then recovers.
    
    The discovery object now sends requests at least once a second if it
    is not in contact with any other nodes, and at least once a minute if
    it has at least one neighbor; if contact with the only neighbor is
    lost, the object immediately reverts to its initial rapid-fire search
    timing to accelerate the rediscovery process.
    
    In addition, the discovery object now stops issuing link request
    messages if it is in contact with the only neighboring node it is
    configured to communicate with, since further searching is unnecessary.
