60337d6 cut the shared props config from 64 to 16 cases for every property to keep bounce_overflow_keeps_a_holder cheap (S12). The shared block is back at 64; the bounce-overflow property gets its own 16-case block, and now asserts that more than SEND_QUEUE_CAP ids left node 0 within one contact, so the table really overflowed.
