This module is an attempt to add tools to Node for handling concurrency using multiple processes. It is inspired by Python's Multiprocessing library. Current features: * It can fork, which means it can run on 2+ separate cores. More coming soon... TODO: * Figure out an IPC API * Figure out a standardized way of handling interrupts and events in sub processes * Figure out how to make this safe and fault tolerant * Windows API, it currently is very unix.
