Subrequests again

[Marat Dakota]

Hi Yichun,

It looks like it's not that simple.

I've traced the source a bit, my post subrequest callback is called
from ngx_http_finalize_request() and this ngx_http_finalize_request() is
called from ngx_http_discarded_request_body_handler() like that (a piece of
code from ngx_http_request_body.c):

    if (rev->timedout) {
        c->timedout = 1;
        c->error = 1;
        ngx_http_finalize_request(r, NGX_ERROR);
        return;
    }

So, I have a timeout and c->error set to 1 and that
means ngx_http_terminate_request().
