AliasIntegrationTest.testClusterStateProviderAPI fails to often

Recent failure rates for AliasIntegrationTest.testClusterStateProviderAPI have been around 4% which is too high. (http://fucit.org/solr-jenkins-reports/failure-report.html). I've beasted 100 runs a couple times and not reproduced it but then hit a failure in it during a normal test run today, so I'm going to start this ticket and record the trace. I have yet to dig through the zips for the logs from the builds.
