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