Update: Tx_Extbase_Persistence_Backend::persistObjectStorage() for 
mm-Relations works like
$this->deleteAllRelationsFromRelationtable($parentObject, $propertyName);

and afterwards adding all which are currently in the storage again.

This is
a, overhead
b, not correct


Furthermore this "re-sorts" the $objectStorage on every persist...

The behaviour of this function seems to be really weird.
