The hunk manages the entire memory block given to quake. It must be -contiguous. Memory can be allocated from either the low or high end in a -stack fashion.

Zone memory functions used for small, dynamic allocations like text -strings from command input. There is only about 48K for it, allocated at -the very bottom of the hunk. - -Cache_???
