I've been working on Storage systems with multi-gigabytes of RAM where you still reason about your memory in much the same way. These systems have lots of RAM but properly intend to make use of all of it. I tend to prefer to allocate on the stack when possible and when the context is right and that works when working in threads or user-space-threads (aka coroutines) that are all hierarchical. It makes some things simpler though you need to care about the stack size and its usage. The places that do need dynamic memory allocations would normally use a memory pool for same sized objects to be allocated from.
