Maybe EntityUsageTable::INSERT_BATCH_SIZE_FACTOR should be changed from 5 to 3/2.5/2?

None of the queries failing with deadlocks seem to be anywhere near the 100*5=500 insert limit, but I guess it's not necessarily the inserts in the logs causing the problems, but the ones that are actually running at that time.
