AFAIK WebDatabase transactions can't have side effects outside the database,
so they can be implemented optimistically with automatic retries so aborts
aren't exposed to the developer.
If localStorage transactions are made to be just syntax around a mutex then
I'm not sure we've gained much for the compatibility break.
