... crash some osds, then restart them ...?
- be lenient about timing out clients if we are laggy ourselves
- mds prepare_force_open_sessions, then import aborts.. session is still OPENING but no client_session is sent...
- rm -r failure (on kernel tree)
- dbench 1, restart mds (may take a few times), dbench will error out.
- multi-mds: the stray dir should be it's own root/base (with /.ceph/mds$n/stray a remote dentry?)
...otherwise mds X can't always push a stray replica to Y and have it fully linked into the hierarchical cache
