I concede I'm still finding my way here and calibrating how much I can get
away with... but I think recall any dissent. I think we *do* have
sufficient consensus and if we just fixed the uniquification of the STI --
or showed that the memory usage wasn't a serious concern in practice so it
could reasonably be left as a later optimisation -- I'd be happy with
committing it and waiting to see who shouts at me for it :)
