Ok. So the rest of the issues remains unaddressed? I am glad that we 
finally settled on the locking. But now I will have to clean this up, 
address the remaining issues, sequence the patches right, provide docs, 
handle the merging issue etc etc? I have seen no detailed review of my 
patches that you include here.

We are going down the same road as we had to go with the OOM patches where 
David Rientjes and me had to deal with the issues you raised?
