When does the connection be closed?

[duyanghao]

boto version 2.34.0.
in the file boto/connection.py:

def clean(self):
        """
        Get rid of stale connections.
        """
        # Note that we do not close the connection here -- somebody
        # may still be reading from it.
        while len(self.queue) > 0 and self._pair_stale(self.queue[0]):
            self.queue.pop(0)

i can't find any code for closing the connection.

may related to #3566

seems there is no way to close the connection now. after clean() the real connection should be closed after gc reclaim that connection object.
