When the defendant is summoned as trustee of the plaintiff, during the pendency of an action, the first action may proceed so far as to ascertain by a verdict, award, or otherwise, what sum is due from the defendant. Such action shall not be delayed by the trustee process unless the court, for cause shown, continues the same for judgment until the termination of such trustee process or until the trustee is discharged.
