All CLA requirements met.

Hi,

First, thank you for your contribution. To me, these really look like two separate PRs, one for the Interrupt function and one for the Editor example.

Regarding the Interrupt:

1. This requires a test
2. Strictly, the thread-id attribute is unsigned only for Python >= 3.7 and we still support 3.6
3. Also, since the original type is long, the "correct" type is (U)IntPtr on everything but Windows
4. (Not quite sure how far we have to go there compatibility-wise, the current implementation could be fine for the usual thread IDs)
5. Maybe we should just expose the API function directly (i.e. RaiseInPythonThread on Exception objects or so) and make Interrupt use that

Regarding the Editor:

1. Should be in its own PR
2. Should not be in src/
   I didn't read the actual code yet, but a self-contained example like this is definitely a useful addition.

I'd say example of this size should have its own repo.

@filmor any thoughts on this now that the Interrupt PR was separated?
