I have found that there a number if tricks & tips to making AFL code
run as fast as possible on AB... partly to do with AFL itself and
partly to with peculiarities of AB... It's taken trial and error
frankly to work them out...
But I'm now much clearer about how to AB in an efficient manner...
such that pervious code that I found almost unusably slow is now
pretty fast.
