title: QFile read timeout
body: <p>My application needs to read files from a <code>nfs</code> mount point. I'm using <code>QFile::read(BUFFER_SIZE);</code> which works as it is supposed to. The problem is, when the <code>nfs</code> unmounts (patchy network issues), this <code>QFile::read()</code> never timesout resulting in application hang. Any sensible solutions please?</p>
  
  <p>Thanks.</p>
