Rather than info, it looks like a DIY.

Goes like this for me: depends on who; babies sleep anytime, so do old 
folks so I'd guess it depends on lifestyle/function in the community.
In a semi-nomadic group it would make sense that there is a watch all 
the time (predators, eh?), so some adults would be sleeping or waking 
all the time, depending.

Lynnet's idea fits the life of settled farmers/neolithic.
