I agree with both of you. "finished" is ambiguous. "Finished" means the QProcess completed. Let's add completed! That won't ever be confusing...

If my English nuance is right, "completed" would connotate it did what was intended where as "finished" would just mean done. "I'm finished with borrowing the tool, having completed my work with it" 

The fact remains that the developer intention is "when this is over by any means, exit the event loop" is not plainly conveyed by the API.

At a minimum the docs should elaborate that finished() only happens after started, and started only happens if the... process is scheduled?
