    Runtime can decide to defer execution of deferrable mails. For example, to unblock subtask thread as quickly as possible, deferrable mails are not executed during MailboxExecutor.yield() or MailboxExecutor.tryYield(). This is done to speed up checkpointing, by skipping execution of potentially long-running mails.
