Searching the codebase for "LUABOX" reveals that this table is created
in the 'newbox' function in lauxlib.c for the purposes of allocating a
temporary buffer, which may also be stored in a UserData on the stack.
In 'lauxlib.c', under the header "Generic Buffer manipulation" there is
a 'UBox' struct, functions, and macros for for managing these buffers.
