> zero for Erlang w/ 5 digits for RT-JVM

RT-JVM's guarantee scheduling latencies of 2us. Erlang doesn't come close. In practice, stock HotSpot has better latency than Erlang. Erlang's "guarantees" are only in effect when 1) no native code is used, 2) no global effects are used (some process registrations, binary heap, etc.).
