I was hoping to avoid this, since the ptvcursor should already be
implicitly scoped to the tree it is working on. But there are a bunch of
call sites where the passed tree can be NULL (?) and a few places where
the tree is explicitly set/reset after creation, so requiring an
explicit scope is safer.

Avoids global memory pools in favour of ones the compiler can verify.
