I see a lot of programs where people disable buffering when they only print to standard output with newlines (or standard error) and never call external programs. (I've also seen a lot of programs disable buffering when they never printed to that filehandle!) Out of the last few hundred pieces of code I've seen, perhaps 5% needed to disable buffering.
