Food for thoughts - unix sockets can use PAGE_SIZEd chunks of memory
(and they do it almost always), which are aligned to 2*PAGE_SIZE due to
alignment issues with skb_shared_info, so unix sockets waste 3.5 kb of
memory on each skb. I think it is time to resurrect idea of placing
shared_info inside skb and allow to allocate it from own cache for
special cases, what do you think?
