One issue with merging them is, how do you merge them? Append one?
Attempt to keep them in the order the stuff was printed? What happens
when operating system buffering gets in there?

I've seen enough messed-up merges of stdout and stderr that I'd
generally far prefer to keep them separate, myself.
