I don't know true reason, but I kind of guess it's because
removing an object from a hash is faster than an array when
they have many elements.

Registered variable must not contain invalid VALUE - other than
object, Fixnum, Symbol, true, false and nil.  If you're really
sure that any "Objects" instances never get destructed until
ruby_finalize(), it would not be necessary.  Otherwise, it
causes GC crashes at high possibility.
