EFS DummyParents cause deadlock [was #7521]
Our circular implementation of dummy parents / getParent() in the TGFileStore causes deadlocks with some code walking up the parents axis. Caused, for example, by {code}file.getContentDescription().getContentType();{code} in the NewObjectWizard at info.textgrid.lab.ui.core.dialogs.NewObjectWizard.performFinish().
(Christoph: this is the bug we tried to tackle during the phone conference on Thursday.)
Maybe we could use a singleton root?
