[FLOW3-general] Resources not removed from file system

[Stephen Bungert]

Hello Flow users,

I have an image model. If I delete my image model, the image records 
related resource record is removed from the typo3_flow_resource_resource 
table.

However, the table typo3_flow_resource_resourcepointer is still 
populated with references to files in the file system.

How can I get flow to remove the images from the file system (and the 
references to them in typo3_flow_resource_resourcepointer)?

Thanks for any help!

Stephen.
