| This option specifies the timeout duration for the `mbox_send` API to busy-wait for the |
| remote processor to consume the previous message before sending a new one. If the |
| message is not consumed within this time, `mbox_send` will return an error. |
| Setting this value to 0 or a negative number will cause `mbox_send` to wait indefinitely |
| until the previous message is consumed before sending a new one. |
