This is not true for many devices. Sorry to contradict you once again,
but you would know it if you had any experience working with devices.

Well, it has actionable consequences: if you treat EAGAIN like REDO you
introduce a busy wait, and if you treat REDO like EAGAIN you introduce a
significant slowness. Now that you make me mention it, I remember it was
precisely the reason I introduced REDO: to fix a slowness in resyncs.
