Images not being freed up while browsing long Rowlist

Hi, I've noticed during testing that when browsing a long rowlist with lots of images, the texture memory gets filled up quickly, making the channel feel sluggish / slow.
The items in the rowlist are getting recycled but the images are not getting garbage collected. What can I do so I don't hit the memory threshold?

I am using the command "loaded_textures" to check the total memory that the images take.
The sample app here: https://github.com/andyyu/roku-channel- ... owListTest
also hits the memory threshold extremely quickly.
