That's an impressively small set of changes (fewer than some platforms
and compilers have needed).

This seems to open up a lot of potentially interesting possibilities,
and I think it probably makes sense to try to merge this in so it just
works out of the box.

It would be good to have a more satisfactory solution to the database
locking though.  Maybe that can be mapped to some sort of IndexedDB lock
or named semaphore?  What matters is that all writers agree on the
locking mechanism, so there's quite a lot of flexibility here.
