I've finally debugged this, it was a simple bug in target.c.  We need this:

 @@ -2181,7 +2181,7 @@ user_visible_resume_ptid (int step)
  process_stratum_target *
  user_visible_resume_target (ptid_t resume_ptid)
  {
 -  return (resume_ptid == minus_one_ptid
 +  return (resume_ptid == minus_one_ptid && sched_multi
           ? NULL
           : current_inferior ()->process_target ());

I'm folding that into the main multi-target patch, which introduces
that function.

Thanks,
