Memory management using Res and Row

My application establishes a connection at the beginning of processing, then uses that connection to do several thousand operations involving reading and updating stored data. I use the Query, Result and Row objects. When the application exits, I seem to have a lot of un-released memory (leaks) that appear to be holding items read from the database during processing. The manual indicates that a ResUse object contains a purge() method to release the resources held by the object, but I can't seem to find similar methods for Result, Row or Query. Do such methods exist? If not, how is this allocated memory freed?
