+The modules in the GGS are built to be capable of redundant operation.
+ By adding a backup process to sensitive processes, the state can be kept
+ in the event of a crash.
+ The coordinator of the GGS prototype has this backup feature built in.
+ The coordinator passes state along to the backup process which keeps the
