This is the memory management component of the Move Engine. It contains a high performance malloc/free replacement and having first class heap support (both of which are provided by rpmalloc, a high performance public domain memory allocator), as well as an implementation of a "tagged heap", as described in Naughty Dog's 2015 GDC Talk Parallelizing the Naughty Dog Engine Using Fibers.
Additional documentation will be added later.
