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

674- * maximum chain length based on the *new* (doubled) bucket count.
675- * In fractions this is just n/b (n=number of items,b=new num buckets).
676- * Since the ideal chain length is an integer, we want to calculate

685- * so now we can write this with a bit shift and logical AND:
