If we did that then (on Windows) every DROP TABLE would take one extra
checkpoint interval to take effect in terms of freeing disk space.
Not sure if this is a good tradeoff for avoiding some file opens.
In any case, I think we should leave it to be debated after we see what
the Windows file-closing solution turns out to be. It might become a
non-issue.
