I fear that the shared memory backend would be more complicated than just this.
As the memory will be at a difference place in the address space, we won't be
able to use pointers. So it looks like we'll need to have some arrays with
different kinds of data and index them or have offset pointers or something like
that.

Anyway, I'd like to propose not to do these optimisations of the tree before we
design the new (shared memory) tree, unless we have a really good reason to do
them now.

With regards
