Hello world upload_module adds 2 sec delay to file uploads

[Valery Kholodkov]

What are the other debug log messages? I'm not sure I can give relevant

To debug the problem I modified the upload_module code and added a debug statement at the end of function ngx_http_upload_handler, and another at the beginning of the function ngx_http_read_upload_client_request_body_handler.
