I disagree, because one does not get to the bottleneck being _the efficiency of extracting memory from one process and transferring it to another_ without major fizzbuzz-specific optimizations first.

For example, there's a clever bit representation to get base-10 carries to happen natively.

The initial competition requirements are not particularly vague about this point: Measuring throughput with `<program> | pv > /dev/null` is prescribed, and it also says

> Architecture specific optimizations / assembly is also allowed. This is not a real contest - I just want to see how people push fizz buzz to its limit - even if it only works in special circumstances/platforms.
