Changes with Apache 2.0.17-dev
+ *) Changes required to make prefork clean up idle children properly.
+ There was a window during which a starting worker deadlocks when
+ an idle cleanup arrives before it completes init. Apache then keeps
+ trying to cleanup the same deadlocked worker forever (until higher
+ pids come along, but it still will never reduce below the deadlocked
+ pid). Thus the number of children would not reduce to the correct
+ idle level. [Paul J. Reder]
