Hi Antony, all

I'm seeing some weird crashes when I test stuff by hand though, I'll dig 
further into that.
Also wondering what happens if you modify a backing table during a graph query?
Perhaps the graph engine needs to, if the backing table is InnoDB, open it 
within a transaction to get a consistent snapshot. We might even need to insist 
on InnoDB to make it work that way.
Otherwise a race condition is pretty much unavoidable in the real world - 
locking is not an option.

Antony, can you clarify how this works?

Cheers
Arjen.
