In short- We have a "parent" which does little else aside from setting a maximum runtime for the "child" (where the task code runs) and the "parent" has a easy to use interface that is resilient to errors.

Rough example:

var task = require('task');

// internally the task operations are done in a different process so we can isolate errors to just that process
task.perform('name-of-task-module', TaskOptions, Job, Project, function(err, result) {

});

Requesting formal review...

This piece handles many different error cases (there is only one success case):

- sync error during startup/run
- async errors (passed and unhandled)
- process unexpectedly closes
- timeouts
- process errors (ipc failures very rare)
