Which version of nginx are you using?

There's no way to release all the memory of a subrequest instantly
because nginx subrequests share the same memory pool as their parent
request. So for long-running requests that issue a lot of serial
subrequests, there will be a good chance of temporary memory leaks in
the lifetime of the main request.

It's worth mentioning that the ngx_lua cosocket API does not suffer
from this issue because Lua GC handles the resource lifetime there.
