Especially in 1.8, the garbage collector can decide to finalize an object even as we are in one of its methods. This means it can free a remote while we're in one of its calls, as we're referencing the pointer inside the object, rather than the `Remote` itself.
We need to use `runtime.KeepAlive()` which only exists past Go 1.7. Furthermore, Go 1.7 is the latest supported by the language team.
