if you want POSIX, import posix, not os

consider the original:

    it's called "unlink", and it's implemented by the "nt" module on
    your computer. look under "posix" for a description, and don't
    forget to access it via the "os" module to make sure your code
    is portable. (1.2)

which later become:

    while that function is actually implemented by the "nt" module
    on your computer, it's documented under "posix".  by the way,
    access it via the "os" module to make sure your code is portable.
    (1.5)

with:

    you'll find that function under "os" (1.5.2)

or Dan's preferred:

    you'll find that function under "os", unless it's a posix-
    specific function. (1.5.2+?)
