Ok, I found the problem. Completely my mistake, because I was running
through the test without being careful.

On the first recovery attempt, I left the postmaster.conf, including the
archive_command setting, in the data dir along with some archives in
pg_xlog. When I started recovery, it overwrote some of my archived
segments.

The archive script isn't supposed to overwrite existing files, but I had
a typo in the check and didn't realize it because in the normal case
everything was archiving correctly.

Would it make sense to throw an error if there's a recovery.conf and
files already exist in pg_xlog?

Thanks for narrowing down the problem for me.
