Thanks for all the responses.

I'm wondering if something is broken since Arasan is having such a hard time
with these positions, especially the last one (f4).

Actually I think the copy of Arasan 5.4 I was running on the Xeon was bad,
because I retried the third position on the Athlon 1.3GHz I usually use, and it
found f4 in 19 seconds (ply 10). The other positions still take a long time,
however.

I'm still investigating. Arasan 6.0 has some experimental forward pruning.
Generally it does well on test suites but this position may be showing up a
problem.
