* The code for writing to the containers and keys tables ensures that the
* row IDs are allocated monotonically (by forbidding any other
* transactions from writing simultaneously with an EXCLUSIVE table lock).
*
* Rather than storing a list of (container, key) pairs which have yet to
* be tested (or have already been tested), which would take O(n*m) space,
* the containers/keys are tested in order. This means we only need to
* store the IDs of the last container/key tested.
*
* If the container/key combinations are represented as a matrix, it looks
* like the diagram below:
*
* containers ->
* +----------+----------+
* k |##########| |
* e |##########| A |
* y |##########| |
* s +----------+----------+
* | | |
* | | C | B |
* v | | |
* +----------+----------+
*
* The shaded are represents combinations that have already been tried.
*
* When a new container is inserted, we test it against every key in the
* shaded area (quadrant A).
*
* When a new key is inserted, we test it against every container in the
* shaded area (quadrant C).
*
* If keys and containers are inserted simultaneously, we take care to
* avoid testing them twice (quadrant B) by testing new containers against
* all keys but not vice-versa.
*
* This code can't tolerate new IDs being inserted while it runs, so it
* locks the tables in SHARE mode. This prevents the import process from
* running (which takes EXCLUSIVE locks) but allows other processes to read
* from the tables.
