message:
Get the test suite running cleanly again.
Found a small bug in the add_delta_source code, seem to have sorted out the rest.
No more 'bucket' based code in the tests. We don't yet limit hash buckets,
as I have to sort out the best way forward for that. (short-term caching of what
buckets are 'full' and flushing them at the end, etc.)
