I'm not sure why the node that is created by the current thread is not
available. I assume that some other thread using XA transactions is committing
changes while the current thread creates the node. The changes from the
committing thread then overwrite the node that has been modified by the current
thread. The write lock is somewhat bypassed in that case.
