```//Michael scott queue
//The ordering of the content of the queue is abstracted in order to keep the system depth-bounded.
//The queue Q have 4 kind of ougoing pointers:
//M: middle (any node that is neither the head nor the tail)
//T: the tail
//A: after (node being enqueued)
//the difficulty is that X.next mith be different thing depending on wheter the queue is empty or not.
//we need to do some case splitting (or use inhibitors)
//to avoid A getting replicated we need to give A the NULL value when it is null.
//to avoid T+H+deq chain, we need to remove the nodes when it gets dequeued.

//D6:         if head.ptr == tail.ptr // Is queue empty or Tail falling behind?
//D7:            if next.ptr == NULL  // Is queue empty?
//D8:               return FALSE      // Queue is empty, couldn't dequeue
//D9:            endif
//                // Tail is falling behind.  Try to advance it
//D10:            CAS(&Q->Tail, tail, <next.ptr, tail.count+1>)
//D11:         else           // No need to deal with Tail
