Calling a C function like `rb_class_new_instance' doesn't equate to a
method call.  The latter involves pushing on the ruby stack, the
former doesn't.  Same thing would happen if you called rb_ary_each in
a similar situation -- the block would be "propagated" when you may
not want it to be.  Using `rb_funcall' to call Foo#new will work; I
don't know if there's a better way.
