  * Expiry of cached objects and execution of prefetcher

+ * XXX: Objects can linger on deathrow as long as a slow client
+ * XXX: tickles data away from it.  With many slow clients this could
+ * XXX: possibly make deathrow very long and make the hangman waste
+ * XXX: time.  The solution is to have another queue for such "pending

+ * XXX: are ready.
