  3. A portable way is to use file locking (although the APIs are different for
    Windoze/POSIX). An application starts, creates a file with the same pathname and
    then tries to lock it. If locking succeeds this is the first instance of
    application. When the application terminates for any reason the operating system
    releases the file lock.
