RAII has a lot of costs associated with it that I am often surprised go 
completely unrecognized by the RAII comunity:

1. the "dec" operation (i.e. shared_ptr) is expensive

2. the inability to freely mix pointers allocated with different schemes

3. slices become mostly unworkable, and slices are a fantastic way to speed up a 
program
