    Refactor logging in loop to only log debug messages once

    Logging entries in a loop to a file can be expensive for a large
    number of objects (e.g. ports) in a loop. Rather than perform the
    overhead of logging a debug entry for each line within the hosts
    file, move the debug trace of the contents to after the loop to
    bulk up the I/O operations.
