+ * the hash function as it applies to the key domain).
+ *
+ * With the items distributed into more buckets, the chain length

+ * The calculation of tbl->ideal_chain_maxlen below deserves some

+ * Since the ideal chain length is an integer, we want to calculate

+ * hash, so to calculate ceil(n/b) with integers we could write
+ *
+ * ceil(n/b) = (n/b) + ((n%b)?1:0)
+ *
+ * and in fact a previous version of this hash did just that.
+ * But now we have improved things a bit by recognizing that b is
+ * always a power of two. We keep its base 2 log handy (call it lb),
