>
> {{NetUtils.wrapException}} is designed to aid debugging by including
> exception diagnostics in the wrapped & relayed exception.
> When a BindException is caught, we build the new exception but don't include
> the original as the inner cause.
> this means it doesn't get logged, and while the host:port problem may be
> identifiable, the bit of the code playing up is now harder to track down.
