As for sk_buff cow break, we need to look at which network paths do it
(netfilter obviously, probably others) and decide whether we just want
to declare that the feature breaks network block IO, or fix the feature
so it plays well with reserve accounting.

I would suggest to consider skb cow (cloning) as a must.

That should not be any problem, since skb's (including cowed ones)
are short lived anyway.  Allocating a little bit more memory is
fine when we have a guarantee that the memory will be freed again
shortly.
