SharedBuffer: Split the creation and share steps
This allows us to seal a buffer *before* anyone else has access to it (well, ok, the creating process still does, but you can't win them all). It also means that a SharedBuffer can be shared with multiple clients: all you need is to have access to it to share it on again.
