Hello Shuxin,

I have seen the same issue before. As far as I can tell this is simply a
bug instead of by design (correct me if I'm wrong). I can also confirm that
nginx will leave behind the listening socket file when terminated with
SIGQUIT. There has been a bug report opened more than a year ago (
https://trac.nginx.org/nginx/ticket/753) but still not being fixed.

Thanks,
Datong
