Where is the problem? In my FixedHandler experiment, non-extensible proxies
are also required to have a finite set of properties.

FixedHandler makes use of a plain ES5 (thus finite) object to store the
non-configurable properties. While the object is finite, as long as it's
extensible, it can grow without bounds. Of course there is a space leak
issue here, as I mentioned earlier, but is there some deeper problem I'm
