Good point.  Then it would probably suffice to move the implementation of 
MLton.CallStack.current to <src>/basis-library/prim-mlton.sml, also do the 
non-trivial setExtendExtra in <src>/basis-library/prim-mlton.sml, and, for 
the emergency handler, hand off the entire call-stack array to C to 
look-up and print the source strings.
