Like the previous change to the FIle interface, we treat Read as if it were an
accessor, we remember the content part but not the error part, and we may fill
it in asynchronously, so this change makes it explicit.
In the future we should probably trap the error in the read and push it back
through another channel though, it will be the root cause of later errors.
