Node's cluster module is handy, but it's a workaround for the fundamental weakness in Node - the entire thing's built on top of a single-threaded event loop which blocks. Instead of just communicating across threads to do some async busy work, you now have to communicate across processes... along with heartbeat monitoring of those processes and endless debate over which IPC mechanism to use.
