I hate pointless "goto exit;" labels, but there isn't a rule against
them and I feel like this is not a good enough patch on its own.  There
is so much other stuff wrong with this function.  It probably *should*
have some error handling for example.

I don't think this patch really adds enough value.  Take a look at the
function and almost every line can be improved...
