One sample patch attached, only compile tested.

I can also work on this but I'll be slow in making progress, so I'll add it
into my todo.  If you can help to fix this issue it'll be more than great.
No worry on the ownership or authorship of the patch if you agree on the
change and moving forward with this when modifying - just take it over!

Thanks!
