title: Memory usage in gwt
body: <p>I´m new to GWT and have a few questions about memory usage in GWT.</p>
  
  <p>Is it possible to detect, how much memory is left in the gwt client (browser)?
  Is there an event if the browsers memory gets low, as a signal to free resources?</p>
  
  <p>Is there a known approximation value how much memory can be used in different browsers, especially mbile ones?</p>
  
  <p>Tnx</p>
