Is the guy who is slugging it out doing ops to keep something from falling over or is he adding features to the "legacy" (i.e. was already deployed before we were hired) implementation. I'm probably being a little naive, but if feature work isn't ongoing, I'd expect that guy heroically slugging it out to make incremental progress in stabilizing the thing so that he didn't need to spend all day at a terminal babysitting a computer program.
