Telling to creator of Redis that they might want to reevaluate their respective program logic (Redis) is pretty funny, only on HN :)

Haha, the question makes sense per se but there are definitely times where you want to see the output in real time. I'm a big fan of printf-debugging :D

It feels good to hear support for printf-debugging coming from such esteemed corner. I have been doing that for a significant majority of my career instead of dropping into debugger. The side effect is you become pretty good at crafting meaningful logs.
