<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">When loading a file, config_hook_exec is not called until we are positive that the configuration loaded successfully.
Similarly, I don't think we would want to call config_hook_exec on writing to a config file until we knew for sure that the file had been written correctly. Otherwise, we may get into a situation where a config hook is notified of the changes, updates itself with the new configuration, but the write fails, resulting in a mismatch between the config file owner module and whatever had hooks into it.
I'd put the config_hook_exec as the last entry in this routine.</pre>

This prevents changes in one module that are intended to be permanent from going unnoticed by another interested party.</pre>
