I would like to learn a bit more about rb_gc_mark(). In my experiments
such a function is never executed if the object is not assigned to a
variable or stored in a hash/array/whatever. But, in case it's stored
somewhere, then the mark() function is executed multiple times by
Ruby.

Is it the normal behavior?
