We had a long discussion in https://issues.apache.org/jira/browse/SPARK-26019
regarding a race condition that happens 
around https://github.com/apache/spark/blob/master/python/pyspark/accumulators.py#L289 

The fix I created here -
https://github.com/apache/spark/pull/23113/files
basically changes bind_and_activate to False 
in SocketServer.TCPServer.__init__'s call 
and manually doing 
            self.server_bind()
            self.server_activate()
            self.serve_forever()
in that thread instead of main thread. 

We have a fix, but we're not sure if this is a bug in Python with multithreading / handling SocketServer.TCPServer ?

Thank you.
