In jcr cosmo, the root collection is dirtied when a resource is added.
In hibernate cosmo, only the resource is dirtied.  This means a simultaneous
put of A and B to collection C will work no problem.  The only problem
occurs when there is a simultaneous put of A and A...then the first put
to A wins, and the second will result in a stale-object exception, which
will ultimately lead to a 500 being returned.  The probability of two
simultaneous puts to the same resource is pretty small, but it does exist.
