We do need research here. And it's not just lifetime info; it's also 
cache pollution. I looked for relevant recent work and found NightWatch:

Liao X, Guo R, Jin H. Enhancing the Malloc System with Pollution 
Awareness for Better Cache Performance. IEEE Trans Parallel Distributed 
Sys. 2017-03-01. 28(3):731-45. http://dx.doi.org/10.1109/TPDS.2016.2587644

NightWatch doesn't do what you want (it focuses on cache-aware malloc). 
Also, it requires Linux kernel mods. Still, it may be useful as a source 
of ideas.
