Subject: Stopping Script Execution


Lets say we have a script like:

for (var i = 0; i < 1000000; i++) {
  // just a waste of time
}

I want to be able to stop the execution of this script. I know if the script
is calling one of my native C functions, I can return JS_FALSE to stop the
script, but how do I stop a script such as the one above that doesn't call a
native function?

If I close the context/runtime I get an exception.
