Then md will start arrays assuming read-only.  No resync will be
started, no superblock will be written.  They stay this way until the
first write at which point they become normal read-write and any
required resync starts.

uh, i tought a read-only array was supposed to remain read-only, and
that write attempts would fail.
My bad for not testing my assumptions.
