Yes, no more threading issues. You just need to call attachCurrentThread() 
before using PyLucene APIs (see README files about this). The PythonThread 
class is gone.

Jython is a Python VM built on top of Java. PyLucene with JCC is a way to use
Lucene Java classes from CPython, seemlessly. Very different beasts.

With JCC, it's pretty close, as close as I've ever been able to get on CPython 
at least :)

The goal of jcc is to bring handcoded PyLucene to as much an end as possible.
Writing Python extensions of Java classes requires some manual work (much less 
now than before) and extracting all the desired pythonic APIs from jcc 
requires a long command-line + some extensions. I don't see PyLucene going 
away completely in the near future but I already threw out tens of thousands 
of lines of handcoded C++ code in the new PyLucene flavor.

This should work on 10.4.9 just as well. I was being specific about 10.4.10 
because I really haven't tried even building this anywhere else but on my 
personal Mac yet. I intend to give this a try on my old Powerbook G4 next, 
then Ubuntu, then win2k.
