Well, matz encourages (in [ruby-talk:94540]) extension writers to check 
frozen status, but does not say he requires it.

I was just worried that in the future there might be some optimization 
that assumed "obj.freeze" was a promise not to change the object.

In my case, I just want to ensure that the object is not modified by 
user code, but only by my extension.
