Go

Ok, it looks like GOROOT is managed by go. See go env. GOPATH seems like it needs to be managed still.

I've switched over to using go env for my information (OS, ARCH, VERSION). Which seems cleaner and clearer.

Memory

Ok, memory usage is about 1.8MB peak heap usage. (Tokio & non-async), so chunks and write_to work the same.

No leaks. ;)
