00006  * @brief  implementation of a autorecovery scoreboard
00007  * 
00008  * Right now, there are two tables and memory is shared between them
00009  * both.  In the future, they should really share the same memory pool
00010  * and the free lists should have some method for figuring out which
00011  * one a node belongs in.
00012  *
00013  * @todo add a list of the last nodes I've talked to
