19 Any number of memory slabs can be defined (limited only by available RAM). Each
20 memory slab is referenced by its memory address.
22 A memory slab has the following key properties:
30 * A **buffer** that provides the memory for the memory slab's blocks.
33 The memory slab's buffer must be aligned to an N-byte boundary, where
