Hello thank you for the PR, can you elaborate some more on the issue this resolved, with perhaps on some steps on how to reproduce. I just want to make sure I understand the issue and PR fully.

When I set a large number of connections, the function openClientConns may take a long time to execute. During this period, although the program is able to receive the Ctrl+C signal, it cannot terminate the program. The program will only stop executing when the number of connections created exceeds the computer's resource limit.
