pg 3.cs0 maps to [-1,3,2] momentarily, and we get an op. firefly says

2014-10-20 04:02:08.246434 7f0d9f7f7700 7 osd.3 74 hit non-existent pg 3.cs0
2014-10-20 04:02:08.246441 7f0d9f7f7700 7 osd.3 74 we are valid target for op, waiting

because

    if (osdmap->get_pg_acting_role(pgid.pgid, whoami) >= 0) {
      dout(7) << "we are valid target for op, waiting" << dendl;
      waiting_for_pg[pgid].push_back(op);
      op->mark_delayed("waiting for pg to exist locally");
      return;
    }

but then the op never goes away because the pg never does get created on this node. this code is
all refactored in giant so the same problem doesn't exist there.
