Well, if your RedHat and are paying someone to work on this feature in Linux, then yes. [1] Irrespective of my disclaimer, many companies are investing many smart people in making Linux work well.

Anyway, I've heard rumors that Windows 8 has this, but I can't find a good source on that (admittedly, I'm spoiled with GNU/Linux where it does not take much work to find this stuff).

[1] I just pieced this together, so take it with a grain of salt. Following the e-mail at [2], I guessed that Frederic Weisbecker was running this project. Googling him brought me to his github profile [3] which indicates he is with RedHat. Anyone who actually knows what is going on please confirm or correct this.

Windows 8 pushes out the tick. See "Idle Hygiene" here:
