Review Comment:
> try block for creating and closing is better.
We need the created socket on return, so "try-with-resources" statement is
not going to work here.
> what's the expected behavior when closing sock on exception? catch and
throw out of the function?
I think it should be catch-and-swallow. `Socket::connect` failure is the
reason to retry.
