 * @brief  implementation of a autorecovery scoreboard
 * 
 * Right now, there are two tables and memory is shared between them
 * both.  In the future, they should really share the same memory pool
 * and the free lists should have some method for figuring out which
 * one a node belongs in.
 *
 * @todo add a list of the last nodes I've talked to
