1.2 00:04:49 We now figure out how far to undo based on generic state information
gathered at runtime.
Also a few bug fixes.
2004/10/22 mbalazin - SUnion and SOutput now both inherit from an SControlQBox that holds all
the common stuff for boxes with an output control stream
- ConsistencyMngr now listens for inputs from both types of control streams.
- SOutput signals when reconciliation is completed (instead of SUnion)
- Also bug fix when suspending data path.. cannot suspend it completely
or control messages don't get through
