hello ...

this is an absolutely non-starter. the WAL is designed to be "hyper  
ordered" and hyper critical. once you fuck up order you will end up  
with a total disaster. WAL has to be applied in perfect order without  
skipping depending objects and so on. any concept which tries to get  
around those fundamental law is either broken.
