Sorry that's not true.

It's like marking it NO_INTERIOR while it being still SCAN. By default, 
all the pages would be marked if the sample pointers to the pool are 
still alive.

And so the objective is to be able to skip collections. How many 
collections are executed only to recover only 1-2% of the memory?
