Writing Your Own Memory Allocators in C++

I’ve recently started working on a new game engine and, since I have no restraint, task zero was writing custom memory allocators. C++’s built in malloc() and new are great tools for getting a hold of raw memory, but they don’t leave any room for customization or optimization based on how that memory is utilized. Custom allocators perform the same job in a context-aware way, which provides the opportunity to take shortcuts malloc() and new never could.
