    Stupid port ranges! Make per experiment range larger. · 484edfc0

    We need to get rid of this!
    
    Since BSD jail days we have attempted to partition up the UDP/TCP port
    range among vnodes as jails and their host shared the same namespace.
    Originally we supported a range of 256 per experiment which wound up
    limiting the number of experiments we could instantiate. In order to get
    a class up and running where we expected a large number of single-vnode
    experiments, I reduced the range to 32 to allow more experiments, forgetting
    that we pick a unique port per-vnode from that range to use for sshd.
    So as a result I limited the number of vnodes per experiment to 32!
    
    Did I mention that we need to eviscerate this mechanism with extreme
    prejudice?
