+     * \defgroup slices_allocator_fns Slice Memory Allocator
+     *
+     * An efficient way to allocate groups of equal-sized chunks of memory.
+     *
+     * Memory slices provide a space-efficient and multi-processing scalable
+     * way to allocate equal-sized pieces of memory, just like the
+     * MiniGUI's block data heap (\a block_heap_fns). Relative to the
+     * standard malloc function and block data heap, this allocator can
+     * avoid excessive memory-waste, scalability and performance problems.
+     *
+     * Note that this implementation is derived from LGPL'd glib.
+     *
+     * To achieve these goals, the slice allocator uses a sophisticated,
+     * layered design that has been inspired by Bonwick's slab allocator
+     * ([Bonwick94](http://citeseer.ist.psu.edu/bonwick94slab.html)
+     * Jeff Bonwick, The slab allocator: An object-caching kernel
+     * memory allocator. USENIX 1994, and
+     * [Bonwick01](http://citeseer.ist.psu.edu/bonwick01magazines.html)
+     * Bonwick and Jonathan Adams, Magazines and vmem: Extending the
+     * slab allocator to many cpu's and arbitrary resources. USENIX 2001)
+     *
+     * It uses posix_memalign() to optimize allocations of many equally-sized
+     * chunks, and has per-thread free lists (the so-called magazine layer)
+     * to quickly satisfy allocation requests of already known structure sizes.
+     * This is accompanied by extra caching logic to keep freed memory around
+     * for some time before returning it to the system. Memory that is unused
+     * due to alignment constraints is used for cache colorization (random
+     * distribution of chunk addresses) to improve CPU cache utilization. The
+     * caching layer of the slice allocator adapts itself to high lock
+     * contention to improve scalability.
+     *
+     * The slice allocator can allocate blocks as small as two pointers, and
+     * unlike malloc(), it does not reserve extra space per block. For large
+     * block sizes, mg_slice_new() and mg_slice_alloc() will automatically
+     * delegate to the system malloc() implementation. For newly written code
+     * it is recommended to use the new `mg_slice` API instead of malloc() and
+     * friends, as long as objects are not resized during their lifetime and
+     * the object size used at allocation time is still available when freeing.
+     *
+     * Here is an example for using the slice allocator:
+     *
+     * \code
+     * char *mem[10000];
+     * int i;
+     *
+     * // Allocate 10000 blocks.
+     * for (i = 0; i < 10000; i++)
+     *   {
+     *     mem[i] = mg_slice_alloc (50);
+     *
+     *     // Fill in the memory with some junk.
+     *     for (j = 0; j < 50; j++)
+     *       mem[i][j] = i * j;
+     *   }
+     *
+     * // Now free all of the blocks.
+     * for (i = 0; i < 10000; i++)
+     *   mg_slice_free (50, mem[i]);
+     * \endcode
+     *
+     * And here is an example for using the slice allocator
+     * with data structures:
+     *
+     * \code
+     * MyStruct *array;
+     *
+     * // Allocate one block, using the mg_slice_new() macro.
+     * array = mg_slice_new (MyStruct);
+     *
+     * // We can now use array just like a normal pointer to a structure.
+     * array->data            = NULL;
+     * array->len             = 0;
+     * array->alloc           = 0;
+     * array->zero_terminated = (zero_terminated ? 1 : 0);
+     * array->clear           = (clear ? 1 : 0);
+     * array->elt_size        = elt_size;
+     *
+     * // We can free the block, so it can be reused.
+     * mg_slice_delete (MyStruct, array);
+     * \endcode
+     *
+     * @{
