[rvm-research] Regarding GC

Hi,

I have a question. I just want to make if a scenario is possible to happen.
The scenario goes like this.

I have a cycle of linked list. All nodes have id from 1 to 50 and they are
arranged in order. There is a head pointer to a node with id 1. I am moving
this head pointer to node with id 6. Does all the intermediate nodes have
stack root pointing to them at the interim time during traversal?
 for example

fun(head){
head = head->next->next->next->next->next;
.........


}
In this above snippet,  do all of the intermediate nodes 2 through 5 has
stack root ("head") pointing to them briefly? or VM figure out and
calculate the address and move the root from node 1 to node 6 directly?

Cheers
Hari.
