Python 2.4 is required for 2 things:
   - PyLucene threading support
   - wrapped python object release during java object finalization
These are the two cases where PyGILState_Ensure() and is used. In python 2.3, 
this function and its counterpart are available, so it should be possible to 
build a PyLucene on python 2.3 using them. There are two files that have 
conditional python 2.4 code: PyLucene.i and cpp/PythonUtil.cpp. You can 
remove the #if statements there and see how far you get with regard to 
deadlocks...
This is the Python 2.3 bug I was referring to in my previous message:
     http://mail.python.org/pipermail/patches/2004-September/015926.html
