My intention was that it would be cleaned by the TAP framework itself,
since the temporary directories it creates are marked for cleanup. But
it may be that there's a platform dependency in the behavior of Perl's
File::Path::rmtree, too.

Yeah. I've pushed that fix for now, but as you say, it may not survive
contact with the enemy. That's kind of disappointing, because I put a
lot of work into trying to make the tests cover every line of code
that they possibly could, and there's no reason to suppose that
pg_validatebackup is the only tool that could benefit from having code
coverage of those kinds of scenarios. It's probably not even the tool
that is most in need of such testing; it must be far worse if, say,
pg_rewind can't cope with it.
