OK, that's going to make life interesting.  How dire are the results
of not chunking like this?  Is it just that the data won't be
distributed across multiple OSDs and therefore you'll only get one
OSD's worth of throughput?  Or is it something worse?  There might
be a way that we can use the GlusterFS striping translator on top
of the RADOS translator, but since it currently sits one level lower
(still above replication but below distribution) there might be some
issues there.
