'Node concurrently deleted while loading its relationships' error when issuing concurrent 'delete all' Cypher query

This problem is most likely related to issue #872. After running a similar test for a while, I see the following error:

"Node[1877] concurrently deleted while loading its relationships?"

as a result of the following 'delete all' query:

start n = node(*) match n-[r?]-() delete r,n

At this point all attempts to execute that query (both programmatically and from the Data Browser) result in the same error. Nothing appears in the log related to this error.

I then went to the Data Browser and was able to view Node 1877 although all of its properties had been deleted. I then restarted the server after which Node 1877 disappeared (according to the Data Browser). I was then able to issue the 'delete all' query successfully.'

This was a bug in transaction state management in 1.8, it has since been resolved.
