As I wrote some months ago: this is a thing a lot of programs could use
(sed, awk, grep etc IIRC)
Now, we could add a flag for every single program to write unbuffered
(linebuffered) output. Or we could do some (non-POSIX?) magic in libc
to get most of this just fixed by doing a env
LIBC_STDOUT_BUFFERING=line $program or whatever...
opinions about this?
