I'm not terribly concerned about wasting 100KB in pure space (or even
more than that): it's space we don't ever touch or look at, so it's
never brought into RAM. IOW it's very cheap.
OTOH checking what really goes into purespace and why something doesn't
is good, because moving data into purespace is good.

PS: Regarding the recent purecopy of autoload's file names: why not just
purecopy the whole autload list?
