Review Comment:
@dongjoon-hyun I also noticed this problem when testing versions prior to
4.2.6. There's a slight delay when the server executes the "close" operation.
Have you conducted an in-depth investigation into the reason for this? If not,
I will take some time to look into it when I'm available.
