[lsh-0]

I think there is a race condition somewhere. I'm getting this sporadically:

ValueError: underlying buffer has been detached

I have no idea. Maybe I will just stick it in a container. Trying one last thing to see if I can replicate these problems locally

some loris-docker links:

• https://github.com/bodleian/loris-grok-docker
• https://github.com/wellcometrust/storage-service

I still can't figure it out. It has something to do with the /var/log/loris directory - changing the mode on that in setup.py breaks sys.stdout.write, detaching the buffer and then BOOM - fucked.

It shouldn't be trying to create directories and chmod them anyway. I know it's a large project, but geez.

containerisation efforts happening here: #18

urgh - wrong ticket
