> Currently, in the procedure scheduler, we will not schedule any other
> procedures for a given queue if a procedure has held the exclusive lock, even
> if a procedure does not require any locks. For such procedures that do not
> require locks, we prefer that they can be executed directly without waiting
> until the procedure that held the exclusive lock is executed before starting
> to schedule execution. Otherwise, if the procedure holding the exclusive lock
> is stuck, the procedure that does not need the lock will also wait forever.
