Trace perform a traversal backwards over the critical path specified as a table index for the processor upon which this is called.
If msg->saveAsProjectionsUserEvents is true then the resulting path will be broadcast to broadcastCriticalPathProjections() which will then call a reduction to criticalPathProjectionsDone() which will call the user supplied callback.
Otherwise, the callback cb will be called with the resulting msg after the path has been traversed to its origin.
