INDEXER_TASKS_RUN event for index-time hooks

The event INDEXER_TASKS_RUN is fired by lib/exe/indexer.php when a page is viewed. Plugins should only hook BEFORE the event if it is important for the task to be run as often as possible. Otherwise, hook AFTER the even to be run only when other tasks have completed.

Plugin authors must call stopPropagation() and preventDefault() if any work is done. If your plugin does nothing, then you must allow the event to continue. Not following these rules may cause DokuWiki to exceed the PHP execution time limit.
