V8 has some quirky memory mechanics. Object pointers, and similar, are subject to a vague hard limit, loosely defined by `--max-old-space-size` and other related flags, while the objects themselves can extend beyond it. For example, if you had 1 object that contained 15gb text, that would likely be OK, however if you had 1 billion objects, storing 1 character each, that would likely lead to a crash - even if the process memory is below limits. Relatedly the shape and nature of the data matters (nesting, types, etc.), limiting the ability to use the full memory available in various ways. I imagine a lot of it has to do with GC, but I don't think that's the full story.

Have you noticed such quirks building loki? Do you imagine being able to make full use of, say, a 64gb ram server? Is this something being taken into account and optimized in the project somehow? @joeminichino
