  # For now, use a hash as the centralized collection point for data. We
  # can't use a method on the module because Celluloid will block that call
  # until after whatever method is currently running, which could be
  # unacceptably slow. We could use a fancy thread-safe data structure
  # instead of a hash, but the GIL means hash assignment and reading are
  # safe as long as we're on MRI.
