I kinda disagree. At least some of the article is specific to Linux's console implementation. Not the "why", but the specific workaround given for the terminal doesn't necessarily generalize to other POSIXs. I think it's fair to specify that in the title. And the complexity of the article's answer is certainly interesting to people who care about receiving keyUp events.
