-** About the realloc function:
-** void * frealloc (void *ud, void *ptr, size_t osize, size_t nsize);
-** (`osize' is the old size, `nsize' is the new size)
-**
-** Lua ensures that (ptr == NULL) iff (osize == 0).
-**
-** * frealloc(ud, NULL, 0, x) creates a new block of size `x'
-**
-** * frealloc(ud, p, x, 0) frees the block `p'
-** (in this specific case, frealloc must return NULL).
-** particularly, frealloc(ud, NULL, 0, 0) does nothing
-** (which is equivalent to free(NULL) in ANSI C)
-**
-** frealloc returns NULL if it cannot create or reallocate the area
-** (any reallocation to an equal or smaller size cannot fail!)
