    connections: replace connection_discard() with connection_delete_unused_instance()
    
    Merge in update_state_connection()'s code skipping connections being
    revived, and adding a whackfd (only add the whackfd when the
    connection really is being deleted).
    
    Add pexpects() to delete_pending()'s call.  Should the pending whackfd
    be passed in?
