- * Simple array based allocator - preallocates a number of elements and you can
- * never allocate more than that, also has no locking.
- *
- * Handy because if you know you only need a fixed number of elements you don't
- * have to worry about memory allocation failure, and sometimes a mempool isn't
- * what you want.
- *
- * We treat the free elements as entries in a singly linked list, and the
- * freelist as a stack - allocating and freeing push and pop off the freelist.
