Yes, this is how I did it in Chandler:

class RepositoryThread(threading.Thread):

     def run(self):

         from lucene import getVMEnv
         getVMEnv().attachCurrentThread()
         super(RepositoryThread, self).run()

Another way to do it without subclassing threading.Thread, is to pass in a 
callable instance with the target keyword that calls attachCurrentThread()
in its __call__ method.
