An interesting idea. Surely we need the opposite though, and that

Would it be possible to not "occasionally" consolidate, but actually
do it ongoing, but just one process, thereby always inserting just one
transaction into the normal BTree at a time? Or does that cause
troubles?
I think that option would work. I think it would suffice to do a
"Big.update(Small); Small.clear()" operation before a nightly pack.
It might invalidate every bucket in every cache, but BTrees are
designed to perform reasonably without a cache.
