Thanks for pointing this out.  I dismissed this issue because it this 
situation the "back" pointer doesn't refer to the first element in the set 
list after several insertions and this creates a series of problems which 
may have a solution but better left aside for this type of problem.

I added some code in shifted_ptr::release() which will make it disregard any 
reference count when the destructor is called upon a set deletion.  Now 
everything works fine.
