finding icons in the theme structure we use is rather expensive. that's why 
there is a cache in the first place. sharing that cache between applications 
means keeping all applications fast instead of having each application start 
out slow.

there's also the issue of disk usage which isn't a big issue on single (or low 
user count) laptops/desktops, but matters more on multiuser systems and 
devices.

agreed :)
