I *have* executed Josh's test.  Josh's contents file contains \r\n line
endings.  Perl has the fd set to binary mode regardless of where it is
opened.  So if the file is on a text mode mount it still opens the file
or sets the fd to binary mode giving the results Josh is seeing.  It you
remove the \r from the contents file then the expected results are seen.
