The problem is that the typical case of all data won't use splice
every with your patches as the 4.2 client will always send a READ_PLUS.

So we'll have to find a way to use it where it helps.  While we might be
able to add some hacks to only use splice for the first segment I guess
we just need to make the splice support generic enough in the long run.
