-/**
- * This class wraps the child process and provides a nice interface to
- * communicate with. It takes care of:
- *
- * - Re-spawning the process if it dies.
- * - Queues calls while the worker is busy.
- * - Re-sends the requests if the worker blew up.
- *
- * The reason for queueing them here (since childProcess.send also has an
- * internal queue) is because the worker could be doing asynchronous work, and
- * this would lead to the child process to read its receiving buffer and start a
- * second call. By queueing calls here, we don't send the next call to the
- * children until we receive the result of the previous one.
- *
- * As soon as a request starts to be processed by a worker, its "processed"
- * field is changed to "true", so that other workers which might encounter the
- * same call skip it.
