    client: fix AssertionError when trying to reconnect too quickly after an error · 305dda86
    Julien Muchembled authored
    When ConnectionPool._initNodeConnection fails a first time with:
    
      StorageError: protocol error: already connected
    
    the following assertion failure happens when trying to reconnect before the
    previous connection is actually closed (currently, only the node sending an
    error message closes the connection, as commented in EventHandler):
    
      Traceback (most recent call last):
