Cancel ongoing ngx_http_request_t

[donatasm]

Ok, so I managed this to work, needed to add ngx_http_send_header and
ngx_http_finalize_request:

static void simple_timeout_handler(ngx_event_t* timeout_event)
{
  ngx_int_t result;
  ngx_http_request_t* request;

  ngx_log_debug0(NGX_LOG_DEBUG_HTTP, timeout_event->log, 0,
    "SIMPLE TIMEOUT TIMER END");

  request = (ngx_http_request_t*)timeout_event->data;

  result = ngx_http_send_header(request);
  ngx_http_finalize_request(request, result);
}

Everything work fine, but during the load test, after some time, a SEGFAULT
occurs:

It seems, that pool argument passed to ngx_destroy_pool is not initialized,
any ideas why this could happen?
