Reproducer to github issue on cpython repository
This code create a Thread and run a minimal http server into it.
how to reproduce
The tricky part is in Main.py line 28 class BackendThreadHttpServer method server_close()
when running this code and exiting it with ctrl+c
If BackendThreadHttpServer#server_close() method doesn't call BaseServer.shutdown(self) the thread join never occurred
and so the program never end
