title: Detect when IE11, with its built-in memory leak, runs out of memory (1.5GB recyclable pool)
body: <p>IE11 has a well-documented iframe memory leak. In a SPA, if you are using iframes the memory will grow to about 1.5GB after which time it will slow down until a crash.</p>
  
  <p>My task is to detect when the browser is about to crash and restart the page soon enough. The application is Vue.JS that is embedded inside ASP.NET MVC.</p>
  
  <p>What kind of memory/performance detection is available in browser in IE11?</p>
  
  <ul>
  <li>Some kind of used memory measure library? </li>
  <li>Some kind of performance measuring library? </li>
  <li>Counting created javascript objects?</li>
  <li>Counting created iframes?</li>
  </ul>
  
  <p>Other ideas? Thanks. :)</p>
