- * A short explanation of the data structure and algorithms.
- * An area returned by malloc() is called a slot. Each slot
- * contains the number of bytes requested, but preceeded by
- * an extra pointer to the next the slot in memory.
- * '_bottom' and '_top' point to the first/last slot.
- * More memory is asked for using brk() and appended to top.
- * The list of free slots is maintained to keep malloc() fast.
- * '_empty' points the the first free slot. Free slots are
- * linked together by a pointer at the start of the
- * user visable part, so just after the next-slot pointer.
- * Free slots are merged together by free().
- *
- * Since modern processors prefer 8-byte alignment, we now pretend
- * our pointers are 8 bytes wide.
