Hi,

I have been following these discussions but not read the patch in detail.

This patch makes me worried especially with the new issues recently 
uncovered. This was already a quite big patch and to fix these issues it 
will likely have to become even bigger and given how this would become a 
very rarely stressed code paths I wonder if we can actually ever become 
confident that the patch works in all edge cases.

Something like this need to be easy to understand for us to have any 
hope at all to be comfortable in the correctness. Can we actually do that?

Andreas
