** 'lu_mem' is an unsigned integer big enough to count the total memory
** used by Lua (in bytes). 'l_obj' is a signed integer big enough to
** count the total number of objects used by Lua. (It is signed due
** to the use of debt in several computations.) Usually, 'size_t' and
** 'ptrdiff_t' should work, but we use 'long' for 16-bit machines.
