title: How much is the lifetime of a Service Worker, can it be controlled?
body: <p>I tried to googled and find an anwser but I didnt managed to find a clear answer.</p>
  
  <p>Lets say I deployed a service worker that has a bug, syntax bug which causes my app to not run (and be able to re-register a fixed version of the service worker).</p>
  
  <p>For how long will the buggy sw be on the user's browser?
  Is it a way to define the life-time of a service worker? Lets say to be unregistered/killed by itself after some hours?</p>
