    Description

      Flush do not work well in unix. Change this line of code to make it work. A Flush should not start a AsyncWrite, is supposed to "completeAsyncWrite".

      My application works in 5.2.1. In a commit applied a patch for the asynchronous write, but when my app to a flush data buffer is not sent.
