multiprocessing.managers.BaseManager.connect() takes 20 seconds to return on failure, even if the server refuses the connection.  This is because the function that creates the connection, multiprocessing.connection.SocketClient(), handles ECONNREFUSED by retrying the connection attempt every 10 ms for 20 seconds.

While a 20 second timeout may make sense for *unresponsive* servers, ECONNREFUSED probably indicates that the server is not listening on this port, so hammering it with 1,999 more connection attempts isn't going to help.  In this case, SocketClient() should fail immediately, or -- at most -- retry a small number of times with exponential backoff.
