nginx: src/http/ngx_http_file

annotate src/http/ngx_http_file_cache.c @ 4018:5e544655d97b

The change in adaptive loader behaviour introduced in r3975: now cache loader processes either as many files as specified by loader_files or works no more than time specified by loader_threshold during each iteration. loader_threshold was previously used to decrease loader_files or to increase loader_timeout and this might eventually result in downgrading loader_files to 1 and increasing loader_timeout to large values causing loading cache for forever.
