Dropped requests during HUP signal after version 20.1.0 #3394
Description
When sending a HUP request to my gunicorn process, it drops requests for a moment.
The configuration in question is:
gthread, 2 workers, 1 thread
I also tried manually choosing sync.
It appears that this bug was introduced after version 20.1.0. When using 20.1.0 the HUP signal reloads the workers without dropping any requests. But upgrading to any future versions does drop them for a moment.
