I personally don't set them to NULL in my projects. Some people do and
that seems to be the case in libdvdread. If anything it can probably
hide bugs, for example where you might be doing a double free.

If the consensus is to not set things to NULL after free then they can
simply be removed.

That would probably get my vote...
