    exit status code as an integer.

    If pid is not a children of os.getpid() (current process) just
    waits until the process disappears and return None.

Return disk usage associated with path.
    Note: UNIX usually reserves 5% disk space which is not accessible
    by user. In this function "total" and "used" values reflect the
    total and used disk space whereas "free" and "percent" represent
    the "free" and "used percent" user disk space.
