The following integer configuration options are available. Proper sanity checks
for the chosen values are not written yet, so use them at your own peril:
* `CONFIG_SLAB_QUARANTINE_RANDOM_LENGTH`: `0` (default) to control the number
* `CONFIG_SLAB_QUARANTINE_RANDOM_LENGTH`: `1` (default) to control the number
of slots in the random array used to randomize reuse for small memory
allocations. This sets the length for the largest size class (currently
16384) and the quarantine length for smaller size classes is scaled to match
the total memory of the quarantined allocations.
* `CONFIG_SLAB_QUARANTINE_QUEUE_LENGTH`: `0` (default) to control the number of
the total memory of the quarantined allocations (1 becomes 1024 for 16 byte
allocations).
* `CONFIG_SLAB_QUARANTINE_QUEUE_LENGTH`: `1` (default) to control the number of
slots in the queue used to delay reuse for small memory allocations. This
sets the length for the largest size class (currently 16384) and the
quarantine length for smaller size classes is scaled to match the total
memory of the quarantined allocations.

* `CONFIG_GUARD_SLABS_INTERVAL`: `1` (default) to control the number of slabs
before a slab is skipped and left as an unused memory protected guard slab
* `CONFIG_GUARD_SIZE_DIVISOR`: `2` (default) to control the maximum size of the
