See issue #645 - misleading and distracting exits from dkpy cause support issues.

Looks sane to me, but I'm not planning on testing this. Did you get feedback from people reporting the original problem?

Yes, I think the issue I referenced included a comment from someone saying it seemed to fix the problem for them.

i tested the fix as well and can confirm that dronekit-python scripts now exit gracefully.

I have merged this then :-) @peterbarker or @mrpollo do you have time for a re-release with this change?

[mrpollo]
