Re: path purpose//Re：[patch]fork: subprocess quit when parent died

[洪志道]

Hello!

It's a common case that all the worker processes are still live while the
master process isn't exist.
So I think nginx should continue to work as Maxim said.

Btw, we noticed that nginx.pid is deleted when we do the upgrade command.
kill -USR2 nginx.pid; sleep(2); kill -HUP nginx.oldpid;

What reason?

Thanks.
