Hmm. (Using Saxon 8) When I put the small file as input on the command
line, the process chokes -- Java throws a fit. When I put the big file
on the command line, it runs properly. Interesting.
Probably not important, but I thought I'd follow up with a bit of
empirical results. :-)

I generally find that if you're doing a join then it help to point a

That still leaves the question of which should be your inner loop and which
your outer loop. If you use keys, or if your processor does join
optimization, it shouldn't matter too much.
