+ * This file was at one time responsible for doing all deliveries, but this caused
+ * big problems on shared hosting systems, where the process might get killed by the
+ * hosting provider and nothing would get delivered.
+ * It now only delivers one message under certain cases, and invokes a queued
+ * delivery mechanism (include/deliver.php) to deliver individual contacts at
+ * controlled intervals.
+ * This has a much better chance of surviving random processes getting killed
+ * by the hosting provider.
+ * A lot of this code is duplicated in include/deliver.php until we have time to go back
+ * and re-structure the delivery procedure based on the obstacles that have been thrown at
+ * us by hosting providers.
