<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The config reload can't affect the contact object stored in the data blob held by the scheduler since the contact object is an immutable sorcery object. The scheduler callback would have to request a new snapshot to get the new config value. A config change that disables qualification on the given contact would remove the scheduler entry and then not start a new one since qualify_frequency would be 0 (see qualify_and_schedule()).</pre>
