No, in most cases, it won't shrink. Most of the time, when you free memory, it is returned to a pool within your application for use in future allocations, but not returned to the OS (so it remains mapped into your application's VM space). If, whatever you're doing with that memory is repeatable, and the memory continues to grow significantly each time you repeat, then you may have a leak, otherwise, it's just business as usual and nothing to worry about. -- Clark S.
