So should we make a table of IO_ERROR-like states to avoid code
duplication?  You have to draw a line somewhere...

"cont" moves you out of IO_ERROR.  IO_ERROR is already a non-running
state (all states except RUNNING are non-running), "stop" is a no-op in
non-running states.  I don't like it that much either, but it works.
