// Bits cannot be set to the word boundary (32 or 64) as this
// consumes the sentinel into the value domain. The bucket must
// be able to hold a sentinel that is larger than the bucket count.
// This presents a waste problem in the case of 32, since it will
// cause an overflow into 5 byte links and 8 byte buckets. In this
// case modulo bucketization will become more efficient.
