Verified once again that grpc.DialContext is indeed non-blocking.
However, it checks in a defer stmt that the passed dial is not ctx.Done().
That is highly unusual if the dial is non-blocking.
But it might still happen, maybe because of machine suspend during the function call and before the defer stmt is executed.
panic:
context deadline exceeded
