ConcurrentModificationException when deleting hashes with more than one field

[patpod]

Deleting a hash with more than one field results in a java.util.ConcurrentModificationException.

This is due to the following piece of code in the class ExpiringKeyValueStorage:

public void delete(Slice key) {
        for (Slice key2 : values().row(key).keySet())
            delete(key, key2);
}

public void delete(Slice key1, Slice key2){
    Preconditions.checkNotNull(key1);
    Preconditions.checkNotNull(key2);
    values().remove(key1, key2);
    ttls().remove(key1, key2);
}

The iterator of the row's keySet complains because it is view of the values that get removed with values().remove(key1, key2).
