Related to https://bugs.launchpad.net/nova/+bug/1324793

If an instance is deleted during the boot process then the
instance.refresh() call in the conductor build_instances method should
raise an InstanceNotFound exception.  But as seen in the bug linked
above it can sometimes raise an InstanceInfoCacheNotFound.  This is odd
because it seems to mean that the instance was deleted but if that was
the case then InstanceNotFound should have been raised before the info
cache lookup began.  This behavior could use some further investigation.
