However, in that file, the shared_storage class, contains:
detail::shared_count count_;
IOW, count_, unlike that in shared_ptr, contains no information about the type of pointee_; hence, I can't understand how policy_ptr's smart_ptr<...>, can emulate boost's shared_ptr with existing policies.
What have I missed?
I missed that shared_count takes checked_deleter<U>() in:
template <typename U> explicit shared_storage(U* p) : pointee_(p), count_(p, checked_deleter<U>(), p)
which does contain information about the pointee_. OTOH, it also has an error: 3 args instead of 2. This, as well as other errors, are corrected in the obvious zip file at:

I'll be happy to upload these to the sandbox with David's permission; however, I've not been able to contact him for several days :(
Go ahead and check in your changes. I won't be able to review them for a while though. Dave
