This bug is fixed in python 2.4: 
http://mail.python.org/pipermail/patches/2004-September/015924.html

Even when not creating threads, with PyLucene there is always one extra 
thread, libgcj's garbage collector finalizer thread that may need to call 
into python to release a wrapped python object. It needs to acquire the GIL 
when it does that.
