This saves 16 bytes in the class vs. the old size, but more importantly
allows us to avoid allocating VMCaches and wasting an entire page for
any attribute larger than 32 bytes; instead, attributes can be up to
1024 bytes before we allocate a full page for them.
Unfortunately small files cannot take advantage of this optimization
right now as the cache is always used for them. I added a TODO about
this.
