# Free List builder track length
This commit makes the free list builder track the length of the lists in
the Random case.
# Refactor free list creation.
Minor refactoring to share code between the new free list and existing
path.
# Randomise slab filling
Knowing when a slab is going to become full makes it easier to by pass
the free list entries as protection for OOB writes. This commit
randomises when a slab will become full.
This commit changes two things
* the free list builder can return some fraction of the deallocations
on a slab.
* when there is a single free slab, we can with some probability
allocate an additional slab.
These two combine to make it difficult to predict when a slab will be
free.
