+ Make the garbage collector aware of malloced bytes, to
+ prevent skyrocketing memory use when the program manipulates
+ heap objects that have large amounts of malloc memory
+ attached, like very large bignums.
+
+ * gc.c (MALLOC_DELTA_THRESH): New preprocessor symbol.
+ (prev_malloc_bytes): New static variable.
+ (make_obj): when the value of malloc_bytes jumps by MALLOC_DELTA_THRESH
+ or more since the last gc, trigger gc.
