IOS Javascript Workers High CPU After Terminate()

I have a complex javascript function which could take 1 second, or many minutes sending an answer. So I created a Worker which is working, I'm calling this function from my UIWebVi

Solution 1:

the easiest way to terminate the worker (and be sure of it) would be to inject a boolean expression to cause the code to "exception out" of its main loop (or even return gracefully if there is only 1 or 2 bottlenecks in the code.). and you can perform any required cleanup in a catch block prior to letting it exit naturally.

I personally hate ending threads with functions such as terminate or kill because it can leave things in a undefined state

The call to terminate may get ignored or enqueued for later simply because the worker is using all the resources it can leaving no time for message processing.
