Yes :)

Yup.

Use echo_subrequest POST /foo -f /path/to/file for that (combined with
ngx_upload, maybe).

Yes. Most disk operations will block nginx (or some other processes like php).

Maybe configure only 1 nginx worker and try

ab -c 100 -n 10000 http://...

and check the results? ;)

There will be a "body_file" option for ngx_lua's
"ngx.location.capture" and "ngx.location.capture_multi" Lua functions,
similar to echo_subrequest's -f option.

But nginx may also block even if itself does the disk operations.

A work-around is to start a few more nginx worker processes, just like
how apache and php-fpm has been doing for years ;)
