Given the instance of QJSEngine, how to create new instance with the same state?

@Merssedes I am not a QJSEngine user, but you cannot clone a QObject (by design). You would have to create a new object and manually configure it to match. I do not see a simple way to achieve this.

You can create several instances but you cannot copy them. Though AFAIK, there's usually no reason to have more than one. What is your use case ?

Because QJSEngine is not thread safe, the only way I see for now is to clone original prepared instance for each worker thread. Anything else requires syncronisation between threads, which means interlocking.
