Paul Baclace commented on WHIRR-303:
------------------------------------
What is the precise concern here? ClusterSpec should not see a lot of churn, so
timely publication of references is the most likely problem it could see. If
so, I think performance would not suffer much by adding some synchronization
which has less code impact for how ClusterSpec is used.
Cluster is immutable and that makes it unwieldy to use, but this is worthwhile
in this case since Cluster fields see more churn.
