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.
