I’ve even heard how languages like Java will allocate a massive amount of memory in the beginning, and then turn. Off the garbage collector for the whole day in high frequency trading scenarios.
Having never been in this situation, I wonder how difficult it is to bend a garbage collected language to behave like a non garbage collected one
It's always difficult to have GC and non-GC objects interact seamlessly. You have to allow GC object finalizers to drop non-GC data, and non-GC objects to register GC objects they might reference as temporary roots (keep them alive) or somehow allow the GC tracing pass to discover what they might be referencing. And you still can't involve non-GC objects in any cycles, they have to be neatly self-contained leaf-like or tree-like sections of your reference graph.
