[New-bugs-announce] [issue43759] StreamHandler does not print to sys.stderr immediately

[Nguyen Thai Binh]

New submission from Nguyen Thai Binh <binhnt.mdev at gmail.com>:

When logger.exception() is called in a `catch` clause, it never logs to sys.stderr immediately. Sometimes it only outputs when the program almost finishes. I don't know how to reproduce as it is occasional. Attached is the logging configuration for my program.

Thank you.
