NGINX logs critical for inactive but purged cache entries

[witrin]

I know this is an common problem with NGINX (https://www.miklix.com/nginx/deleting-nginx-cache-puts-critical-unlink-errors-in-error-log/) but is it possible to sync with NGINX internals after PURGE so this "critical" error won't be logged?

@denji Are you looking at completing this enhancement some time this year? Would be really nice to sync NGINX's internal keystone with the PURGE.
