title: Is SpiderMonkey safe for running user-submitted scripts?
body: <p>I've been searching for some way to permit users to write scripts in order to extend my application (written in Go) and so far, SpiderMonkey seems to be the best match.</p>
  
  <p>Unfortunately, its website states that the last standalone release was of the version used in Firefox 4!</p>
  
  <p>My question is if it is safe to run untrustworthy scripts with SpiderMonkey (I will use the operation and stack callbacks to prevent hanging, etc.) Or if there is a better alternative.</p>
