Nginx proxy cache purge process does not clean up items fast enough for new elements

[sachin.shetty@gmail.com]

Thankyou Maxim, is there anyway I can make the cache manager a bit more
aggressive in prune and purge? We already leave 20%  of space free on the
disks, but the concurrent request rate for large files can be huge and we
still run in to this issue. 

What are your thoughts about disabling buffering on such issues? This is not
a fatal error, so we should stop buffering and switch to streaming mode and
let the request succeed with a error log line in error.log. 

Thanks again for your help on this.
