code: func (t *transaction) purgeStalePool(poolId string) {
  	t.script(purgeStalePoolScript, redis.Args{poolId}, nil)
  }
docs: // purgeStalePool is a small function wrapper around purgeStalePoolScript.
  // It offers some type safety and helps make sure the arguments you pass through to the are correct.
  // The script will remove the stale pool from the active pools set, and then requeue any jobs associated
  // with the stale pool that are stuck in the executing set.
