AFAIK there are 3 solutions to this:
1) Modifying every app we want to support with procd + logging
2) Using PTY which I tried in https://patchwork.ozlabs.org/patch/486670/
3) Using LD_PRELOAD

The PTY was pointed as not the best choice, so that's why I continued
with LD_PRELOAD. As Jo-Philipp pointed, it's the same solution
"stdbuf" uses. I'm afraid there isn't any better alternative :(
