in thread RFC: Is there a solution to the flaw in my hash mechanism? (And are there any others?)
Sorry, I mistook the context of that statement due to lazy reading.
Another approach would be a bitmap.
You could even avoid a bitmap by, for example, sharding odd hash values into one hash table and even hash values into a second hash table. Then the 0 bit could indicate "empty" though the meaning of the value of that bit would be reversed between the two tables.
