I have what I thought was a thread-friendly app, and after doing some output I've concluded that of the 15 threads I am attempting to run, only one does.

I have

if __name__ == "__main__":
    fhf = FileHandlerFactory()
    tweet_manager = TweetManager("C:/Documents and Settings/Administrator/My Documents/My Dropbox/workspace/trie/Tweet Search Engine/data/partitioned_raw_tweets/raw_tweets.txt.001")
    start = time.time()
    for i in range(15):
        Indexer(tweet_manager, fhf).start() 

Then in my thread-entry point, I do

def run(self):
    print(threading.current_thread())
    self.index()

That results in this: <Indexer(Thread-3, started 1168)> So of 15 threads that I thought were running, I'm only running one. Any idea as to why?

Edit: code
