I assumed that the reference count was in a struct with the data, 
and refcounted point to it.

In this case, if you remove the pointer via a sequencially 
consistent write (while keeping a local copy internally) and THEN 
decrement the counter, the other thread will access another 
object (or skip on a null check). Granted the read is 
sequencially consistent.
