that has been on my mind for quite some time, but since it breaks
backwards compatibility I wanted to save this for collectd 4. Right now
I have a huge pile of work that demands my attention, but I hope to get
started on this in August.

I don't think I would have done it in a different way..

It's up to you. Since I want to change some more things for the next
major release the patch is likely to not work with it anyway. But it's
always educational to see how other people would have done this ;) Also,
if it's not too much work I might end up cleaning the patch up and
providing it on the website so other people with similar requirements
don't have to pull up their sleeves themselves..
