Same difference: if `cat` can't see it, then the change hasn't been
received by the OS at all (even less so by the underlying disk).

The changes you see in `cat`s output will be transferred to disk
eventually, yes. But those that aren't visible to `cat` just don't
exist, as far as the OS is concerned.
