The 3par driver, for both iSCSI and Fibre Channel, that I will commit soon, needs the lockutils to ensure thread safety in each of the driver entry points. The driver uses a single shared http session for all of it's connections to the 3par drive array. This is required for the driver because of the limitation on the 3par's WSAPI only supporting a very small number of open connections. For example without this, the driver will have problems when 2 users try and create a volume at the same time. I've discovered this in my threaded stress test tool.

To monitor it from a distance: follow @openstack on twitter.
To tame it for use in your own cloud: read http://docs.openstack.org
To study its anatomy: read http://cinder.openstack.org
To dissect it in detail: visit http://github.com/openstack/cinder
To taunt it with its weaknesses: use http://bugs.launchpad.net/cinder
To watch it: http://jenkins.openstack.org
To hack at it: read HACKING
To cry over its pylint problems: http://jenkins.openstack.org/job/cinder-pylint/violations
