What if the API enforced that we restored our state whenever the module
is back in our control.  String handling would be cpu-intensive, but
if the various dispatch modules simply reset the const string to the
same value pointer, this wouldn't be very intensive at all.

I agree in principal, while running within the core, it should be our
choice of state.  Once it enters the users handler or filter code 
(and they have not passed the brigade up the stack yet) it would be
very useful to see their consideration of the current phase.



    ... {module resets phase}
      oldphase = phase
      ... {module's filter mucks with phase}
        oldphase = phase
        phase = oldphase
      phase = oldphase

Forgive the sloppy style, but you get the concept I have.
