However, another loop was inserted more-or-less in the middle of the of the unwiring path. This loop picks up the "entry" loop variable from the first loop without first setting it to start_entry. Naturally, the second loop is never entered and the pages backing the entries are never unwired. This can lead to a leak of wired pages.
