 update time is earlier than the time at which flush_all was set to be
 executed to be ignored for retrieval purposes.
 
+The intent of flush_all with a delay, was that in a setting where you
+have a pool of memcached servers, and you need to flush all content,
+you have the option of not resetting all memcached servers at the
+same time (which could e.g. cause a spike in database load with all
+clients suddenly needing to recreate content that would otherwise
+have been found in the memcached daemon).
+
+The delay option allows you to have them reset in e.g. 10 second
+intervals (by passing 0 to the first, 10 to the second, 20 to the
+third, etc. etc.).
