Some algorithms are tricky, but there&#x27;s a lot one can do without a GC via epoch-based reclamation schemes: <a href="http:&#x2F;&#x2F;aturon.github.io&#x2F;blog&#x2F;2015&#x2F;08&#x2F;27&#x2F;epoch&#x2F;" rel="nofollow">http:&#x2F;&#x2F;aturon.github.io&#x2F;blog&#x2F;2015&#x2F;08&#x2F;27&#x2F;epoch&#x2F;</a> (I guess this could very well be regarded as a sort of application-specific GC, but, if anything, it feels closer to reference counting than a tracing GC).
