one simple little test that i see differing results depending on kernel is
'mkfifo foo ln foo bar'.
Heres a test script that demos that, and output on precise, raring, saucy (no
containers used).
== raring: 3.8.0-27-generic ==

Attaching 'serv.py' which mimics behavior of supervisor/http.py in
supervisor for setting up the socket, and then implements an 'echo'
server. client.py is just a simple client to run and show the problem.
One would expect to be able to do this:
$ ./serv.py /tmp/my-socket
$ ./client.py
I added 'linux' as this is at very least a change in behavior between
12.04 kernel and saucy kernel.

Regarding creating the socket as a non-root user - did you chown the
directory to your user's uid? I have no problem once I've done that in
running the server.
I have the same issue with the client:
sudo mkdir /mnt2 /upper
sudo mount -t overlayfs -o lowerdir=/mnt2,upperdir=/upper none /mnt
sudo
Oh, never mind, I see - that's on precise. and yes I get the same
result all around.
