Oops, I'm sorry, I haven't seen the patch and the answers to it.

According to the comments by Andrew a simplification of this code
section would be nice. I think it should be possible to do this in a
way that the initialize-to-zero won't be needed anymore.

Prabhakar Lad, are you working on this already?
If not I'll take a look at it.
