If you create threads faster than Python and Java can collect the objects 
you leave lying around, then yes.

For instance, closing the store you're opening in every thread instead of 
None'ing it out may have the same effect.

Andi..

Otherwise VM crashes. e.g.
-----------
import threading
import lucene
lucene.initVM(lucene.CLASSPATH)
def threadFunc():
     lucene.getVMEnv().attachCurrentThread()
     _store = lucene.FSDirectory.getDirectory("/tmp/index/", True)
     #_store = None # set to None to avoid crash!

     lucene.getVMEnv().detachCurrentThread()
def main():
     t = threading.Thread(target=threadFunc)
     t.start()
     t.join()
main()
----

I need to call detachCurrentThread because I use threads heavily andI will soon get out-of-memory error if didn't call detachCurrentThread.
