/*
* 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.
