>
> Currently, the operators of async state processing use the main mailbox executor for callback execution, which has low priority. It's better to use the one for `YieldingOperator`, as:
> {code:java}
>         MailboxExecutor mailboxExecutor =
>                 containingTask
>                         .getMailboxExecutorFactory()
>                         .createExecutor(configuration.getChainIndex());
> {code}
> It has higher priority, which could help us do efficient `yield()`.
