[Property Name] ReplaceFlushed [Default Value] False [Description] 
When ReplaceFlushed is enabled, any instances in the pool that are flushed will be replaced immediately so that the pool will remain at its current size. Replacement is done in a background queue so that incoming threads will not have to wait for instance creation. The aim of his option is to prevent user requests from paying the instance creation cost if a flush performed while under heavy load at peak hours. Instances from the minimum side of the pool are always replaced when they are flushed, this setting dictates the treatment of non-minimum instances. A bean may flush its pool by casting the SessionContext to Flushable and calling flush(). See SweepInterval for details on how flush is performed.
