+/**
+ * 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.
