- * Most BAT operations use a BAT to assemble the result. In several
- * cases it is rather difficult to give a precise estimate of the
- * required space. The routine BATguess is used internally for this
- * purpose. It balances the cost of small BATs with their probability
- * of occurrence. Small results BATs are more likely than 100M BATs.
