  // Fields are purged on cron. However field module prevents disabling modules
  // when field types they provided are used in a field until it is fully
  // purged. In the case that a field has minimal or no content, a single call
  // to field_purge_batch() will remove it from the system. Call this with a
  // low batch limit to avoid administrators having to wait for cron runs when
  // removing instances that meet this criteria.
