Comment (by jinmei):

 Replying to [comment:12 jelte]:
 > due to the nature of these buffers, there will probably always be ways
 to shoot yourself in the foot :)

 Right, and although it might be a bit more likely happen in this case
 "due to the nature", but in some sense it's no different from things
 like this:
 {{{#!cpp
     Foo foo; // this is a very complicated class, ctor does some black
 magic
     memset(&foo, 0, sizeof(foo)); // but it's broken here, compiler allows
 it
 }}}

 so, I think it's reasonable to at least prevent the self-disruption by
 the object's own method (and in particular, by a const member
 function).

 > however, i think this is a reasonable compromise, and the code looks ok,
 so please include it, and merge this branch.

 Okay, thanks, merge done, closing.
