> If you know how to do serious software without spilling any memory

This thread is about K8s Pods (and other K8s resources) that have been sitting idle, not memory leaks in software.

As far as "spilling" memory, the problem has already been solved by Rust which does not do garbage collection because it has static memory mapping. Does this mean egregious amounts of memory won't be used by some Rust programs? No. But unlike languages with garbage collection, where Rust is using that memory it is actually doing something with that memory.
