can't destroy before setData has finished

[tepez]

When calling instance.destroy() before instance.setData() has finished there is an error.

This is illustrated here: ​http://jsfiddle.net/sSPe7/1/

There is even no need to call setData() to provoke the error. Simply calling destroy() immediately after creation produces the same error.

This is a duplicate of #11502 and will be closed as such.

We are going to try to solve this in CKEditor 5 (If it will be possible). In CKEditor 4 developer is obligated to api to control this.
Currently it is hard to stop all running processes when they were started (both are complicated) that is why there are events that you should use in such cases - ​http://docs.ckeditor.com/#!/api/CKEDITOR.editor-event-afterSetData, ​http://docs.ckeditor.com/#!/api/CKEDITOR.editor-event-instanceReady.
