Hi Nigel,
Many thanks for your quick reply!
I can reproduce it with what I think is a smallish environment.
If you download my code from here:
http://hg.linux-ha.org/assimilation/archive/tip.tar.gz
Untar it, and go into the cma directory. Run the python script *store.py*
It will fail. Each time you run it, it will give a higher node in the
graph that it cannot find.
If it doesn't fail, then we can try the docker thing to reproduce the
environment more exactly.
To try the docker version, you just need to install docker and say
"docker build ." (or docker.io) with my Dockerfile in your directory.
It will do the rest - grab the OS, libraries, things we need, build my
code and run my tests. It just takes longer. For this environment, it
helps to understand docker when you want to debug it.
It's pretty awesome. But hopefully you won't need to do that.
I also have a more complex set of tests that only require python that
will likely fail if there's a Neo4j/Py2neo issue that affects me. Maybe
I should create a separate test environment for that - that you could
easily run.

Yes. There are lots of ways to do that. After all, it's all open
source :-D.
Are you familiar with docker?

Can you share some code that I can run to recreate the issue?

The context is this:
I just did a commit of a transaction which added nodes to the
database, and am now trying to retrieve these same nodes by
the ids for them which were returned by the transaction.
