OK as is. Room for improvement.

I don’t think we need the variable at all. It’s also strange to use UNUSED_PARAM for this. The word is “delete”, not “kill”.

Also, I think we should have a helper member function to hide the use of "new". I don’t like having these calls to new with the comments in three different places in the file. It should just be one small inline function.

> +    // No need to free the PingLoader object or manage it via a smart pointer - it will kill itself as soon as it receives a response.

Ditto.

Ditto.

Since this is in the class definition, the inline keyword is unneeded.

Since this is only used in the .cpp file, it need not be in the class definition. I can be in the .cpp file, and just be declared in the class definition.
