Still more to come :)

Here's a MIME-64 containing 8 marshalled Floats:
BAhmGjI0LjAwMDAwMDAwMDAwMDAwNAAAAQQIZhoyNy45OTk5OTk5OTk5OTk5OTYA//8ECGYaNDQu
MDAwMDAwMDAwMDAwMDA3AAABBAhmGjQ1Ljk5OTk5OTk5OTk5OTk5MwD//wQIZho0OC4wMDAwMDAw
MDAwMDAwMDcAAAEECGYaNTEuOTk5OTk5OTk5OTk5OTkzAP//BAhmGjU0LjAwMDAwMDAwMDAwMDAw
NwAAAQQIZho4My45OTk5OTk5OTk5OTk5ODYA//8=

File.open(ARGV.shift) { |file|
    begin
        while a = Marshal.load(file)
            puts "#{a.class} #{a}"
        end
    rescue EOFError
    end
}

Output should be:
Float 24
Float 28
Float 44
Float 46
Float 48
Float 52
Float 54
Float 84

Oddly enough, with your patch the first two floats are fixed,
showing 24.0 and 28.0 (which is entirely a coincidence; this
list didn't exist when I came up with the original numbers).
The rest are as shown.

I'd have used ruby's mime-types but I couldn't get it to compile :/
