Dont feel like trying to go through about 80 pages of posts just to find where the devs talk about ways of either getting around the SoD or ways of preventing it for now. Its somewhere within these posts.
The human mind is an interesting thing. There was certainly talk about using wake locks and other tricks to prevent the device from sleeping, however, I recall those being in the CM10 thread and presented as hackarounds for that critical usability issue. That is probably what you are recalling. There was actually nothing implemented in the kernel to keep itself awake in this manner.
So.. its not true, but we forgive you for understandable mistake :good:
