I did a couple of regenerate_caches runs and this does go a bit faster
on my laptop (~9m30 before vs ~8m30 after). The utf8::utf8(utf8 const &)

2.6% if I'm reading things right.
That's a good sign. Unfortunately I cannot reproduce it myself - on
the aforementioned beefy amd64 box, I'm seeing a very small but
consistent slowdown on the same test (4m20 before, 4m21 after).
oprofile is not cooperating with me (zero samples recorded, no matter
what I do), so I don't know why.
Having the utf8 copy constructor jump up in the profiles is to be
expected; this _is_ doing more copying around of utf8s. [Vocab items
in general seem to have a lot of extra gubbish attached to them - .ok
booleans, symtabs, and now Tim's made them all double indirect - whose
value I really have to question...]
I'll try a few initial pull runs and let you know how they go as well.
Cool, thanks!
