Ah yes, of course. Serves me right for not testing it before posting
it! ;-)

Hmmm, that's too bad. It's possible that going down to two WHEREs over
the full array will be faster than using the first WHERE to thin the
array down. It'll depend on what fraction of the array contains zeros
- if there are lots of zeros, then the first WHERE doesn't help you
that much, whereas if there aren't many then it will help a lot.

Is this part of the code really one of the biggest remaining
bottlenecks? I doubt you'll be able to shave much more off of it.
