[Users] AsyncTreeNode without parent...

[Georg Kaspar]

Thanks, but the problem still remains - there are two parent nodes for
each loader:

root o--|--o--o--|--o
        |        |--o
        |        |--o
        |
        |--o--o--|--o
                 |--o
                 |--o

what i need is a way to create a node from a loader only without a
parent node...
