# Doesn't ensure that the tag value of 'aws:autoscaling:groupName' 
# is actually the name of the autoscaling group
def ec2_instances
  instances = EC2::InstanceCollection.new(:config => config)
  instances.tagged('aws:autoscaling:groupName').tagged_values(name)

# Proposed fix. Works but is really slow.
