> I wanted to know if there was a plan to apply that fix also in nginx, cause I see that worker processes are in practise very long to shut down (12 worker processes, when reload signal is sent then it takes more than 3 minutes until the last worker is down), which is a problem in our case.
Yes, this works started in April and was suspended due to switching to other important tasks.

We will finish it shortly.
