Unless I have missed something, intrusive_ptr has the following issues:

1. You must declare intrusive_ptr_add_ref and intrusive_ptr_release as 
top-level functions that take a pointer to your class.  This can be 
problematic if your client class is a nested private class as in my prior 
example.

2. You must define the functionality of those two functions.  While the 
functionality is trivial, it still needs to be done manually for each 
class.  Anything manual is subject to error.

The shared_ptr_embedded and shared_ptr_count pair solve both issues.
