[Bf-committers] Ghostlike datablocks

No (Jeremy) it doesn't work that way.

Blender hardly frees data when "delete", instead it unlinks data. All  
data that has links then still is written in a Blender file.

Sometimes, such links still exist (can be a tree with many brances).  
The unlink options in Blender don't fully check entire trees, instead  
it reconstructs trees on a file read.
The way to get rid of these Meshes is just by 2 save/load cycles. Not  
with Blender quitting inbetween!

(In your case, when you delete a Scene for example, all Objects being  
used by the scene get one 'user reference' less. But the data linked to  
Objects itself remains.)
