    cleanups from reading the crypto helper code
    
    - wrapping our own macro bodies in do { } while (0)
      is more obscure than useful.  Braces will do.
    
    - added comments to show which functions were executed
      within a helper thread and which might be and so
      should be re-entrant.  Likely missed some!
    
    - reformatted some monstrosities
    
    - added some explanations
    
    - renamed some functions to make their purpose manifest
