    Storing a single IPv6 default exit policy
    
    Each server descriptor constructed its own default value for the IPv6 exit
    policy, which was foolish. ExitPolicy instances are read-only instances, so all
    descriptors might as well use the same default. This saves roughly 2.3 MB of
    memory when downloading all of the current server descriptors (or roughly 3%).
