Hi,

I would like to see the attached patch applied to scoped_ptr.hpp.

Rationale:

ptr != p should be a precondition violation. I can't think of a good reason 
why a scoped_ptr should be reset with a pointer that is already taken care of 
by a scoped ptr.

The current code fails if the dtor is called during a call to reset. Yes, 
things like this can happen. The managed ptr will be deleted twice.

Comments?
