Tom,
Ok, we're long overdue for upgrading to 7.1.3 anyway, now I have a real
good excuse to do it.

If you can reproduce this under 7.1.3 or later I'd be interested in
pursuing it. 7.0 is rapidly attaining the status of "ancient history".
Quite aside from plain old bug fixes, the existence of WAL in 7.1 would
make a huge difference in the possible causes of such a problem.
