@deffn Command backtrace node [val]
Trace backwards through a history of last-arriving transitions on
node @var{node}, until a cycle is found.  
If @var{val} is omitted, the current value of the node is assumed.  
Useful for tracking down causes of instabilities, 
and identifying critical paths and cycle times.
