Flex: Is it a memory leak?

tutorial how flash garbage collection works:

heres a couple good quotes from the presentation:

-The collector is not guaranteed to find all collectible blocks in one pass
Don’t want to interfere with rendering and interaction, Thus memory may never return to the initial point

-You are generally only concerned about repeatable sequences: Popup dialogs coming and going Modules loading and unloading. If you repeat these sequences often over a long period of time, the amount of totalMemory will hit some maximum value and stay at or below it if you are not leaking memory.

-Garbage Collection is not predictable
