There's actually always a duality between:

   - Reference counting/mark and sweep
   - Throughput/latency
   - RAII/GC

A good read: https://www.cs.virginia.edu/~cs415/reading/bacon-garbage.pdf

   We present a formulation of the two algorithms that shows that
   they are in fact duals of each other. Intuitively, the difference is that
   tracing operates on live objects, or “matter”, while reference counting
   operates on dead objects, or “anti-matter”.
