 			[GL !7206]
 
+5845.	[bug]		Refactor the timer to keep track of posted events
+			as to use isc_task_purgeevent() instead of using
+			isc_task_purgerange().  The isc_task_purgeevent()
+			has been refactored to purge a single event instead
+			of walking through the list of posted events.

 5830.	[func]		Implement incremental resizing of isc_ht hash tables to
 			perform the rehashing gradually. [GL #3212]
