This is the pointer to the chain of previously freed objects. UUID creation was the slowest part, the optimisations I suggested above seemed to help improve it, at least in my benchmarks. However, because a destructor for an abstract class is always called by the destructor for the base class, pure virtual destructors must always provide a definition. The __del__() method will be implicitly invoked when all references to the object have been deleted, i.e., is when an object is eligible for the garbage collector..
