I'll provide a use case for why this feature is important. I'm working on a implementation of a databased backed CaptchaStore to allow JCaptcha to work in a clustered environment. The current implementation of the AbstractManageableCaptchaService calls the CaptchaStore method getSize three times during the course of generating a captcha, which means that three identical queries are invoked. In addition, the service also maintains a Map of timestamps to do the garbage collection. The CaptchaStore could do this more efficiently by deleting all records older than some timestamp.
