Just to clarify in case anyone gets confused by this, nextTick does not many anything parallel. Node is single threaded and nextTick doesn't magically change that. All it does if defer some work till a later tick. The body of your callback will still block the CPU when it gets called. If anything this will use more CPU overall because of managing the nextTick queue and calling extra callbacks. process.nextTick was not made for this use case, it sortof works currently because of an implementation bug that sometimes lets other events in before the nextTick fires. What's really needed is either true parallel work using threads/processes or an idle event that you can feed units of work.
