I think I meant "must not use" - and indeed memslots must *not* be
mapped as shareable. I'll update to this wording:

  When this capability is enabled all memory in memslots must be mapped as
  not-shareable (no MAP_SHARED), attempts to create a memslot with MAP_SHARED
  will result in an -EINVAL return.
