Hey Till, do we currently have any callers that require "undo" semantics? If we 
don't, we should consider killing the seek's all together. If we do, I'd prefer 
to make the "undoness" explicit by requiring one to pass a bool to 
protobuf::read requesting the undo (which will fail if they also use a file 
descriptor that doesn't let us seek!). We can then make the default to not undo.
