 I'm running a wave-based preprocessor on boost/python.hpp as part of
 document generation (Synopsis). The preprocessing alone takes >6 hours !
 (The subsequent parsing with Synopsis' own C++ parser is then relatively
 quick, surprisingly.

 I notice that wave seems to get increasingly slow, so I wonder whether the
 speed decrease is caused by some internal lookup on a growing dictionary
 (map) that has super-linear lookup time ?
