  # From the mongo driver:
  #
  # > Global subscriptions must be established prior to creating
  # > clients. When a client is constructed it copies subscribers from
  # > the Global module; subsequent subscriptions or unsubscriptions
  # > on the Global module have no effect on already created clients.
  #
  # So, for existing clients created before the Skylight initializer
  # runs, we'll have to subscribe to those individually.
