Great. It was Python evolving which I suspected at the start.

done.

As for new paragraph classes I have been messing with Kuchling's 
tex_wrap and have managed to get the run time down to something 
reasonable. In python I have the time down from over 3.06" to 0.5". This 
just corresponds to the simplest of line breakings. His version doesn't 
do hyphenation or even follow Knuth's algorithm all that carefully.

I believe it should be possible to improve much further. I translated 
simply to pyrex and have the time down again to 0.23". With more 
agressive C style coding that should improve further (perhaps another 
factor of 10 since my pyrex version is still using lots of python 
variables in the main loop).
