You can freely read an older NightWatch paper here:

Guo R, Liao X, Jin H, Yue J, Tan G. NightWatch: Integrating Lightweight and 
Transparent Cache Pollution Control into Dynamic Memory Allocation Systems. 
USENIX ATC. 2015. 307-18. 
https://www.usenix.org/system/files/conference/atc15/atc15-paper-guo.pdf

Although NightWatch's source code is freely readable (it's on GitHub), it does 
not specify a software licence so I have not read it and don't recommend that 
you read it.

Yes, a problem common to many systems papers.

I didn't quite follow your profiling proposals. As near as I can make out you'd 
like to log calls to malloc, free, etc. But for good results don't you also need 
to log memory accesses? Otherwise how will you know which objects are hot?
