Yes, this is the "Plan B" I mentioned in mail last week.
I had explored this. Both on performance and resource grounds,
it is a little worse. Not hugely worse, but if we are going
to improve TLR, then might as well take the best option.
(Another reason to prefer current solution also serves as
a reply to Tom: Yes we don't like using Unsafe just to
bypass package-protection access control. But at least it
is just accessing simple scalars, not references.)
Don't forget it is also writing them... :-(
