  -spec disconnect_node(Node) -> boolean() | ignored when Node :: node().

  Forces the disconnection of a node. This appears to the node Node
  as if the local node has crashed. This BIF is mainly used in the
  Erlang network authentication protocols.

  Returns true if disconnection succeeds, otherwise false. If
  the local node is not alive, ignored is returned.

  Note:
    This function may return before nodedown messages have been
    delivered.
