Interesting. I'd not seen those failures in the configurations I'd
run. I'll look into them (other than that my best bet for debugging is
a kernel panic, this has to be easier!).

It's about 275000 before uniqueing (which roughly matches an earlier
measurement I did). The duplication seems to be dominated by the
halide tests, though you have to be a little careful with "main"
(which occurs about 500 times). At a glance I'd put the total closer
to 53000 (52420 + 492 extra copies of main), but that's a small
difference to your figure.

Tim.
