Fair enough; this certainly knocks off all the important stuff already, 
just wanted final sanity check opinion.  This one is ready for a 
committer to look at now.  My test case seems to work fine with a 
moderately complex set of things to navigate.  The main think I'm not 
familiar enough with to have looked at deeply is exactly how the FSM and 
toast computations are done, to check if there's any corner cases in how 
it navigates forks and such that aren't considered.
