----------------------------------------
[~noble.paul], I want to clarify
https://github.com/apache/lucene-solr/commit/3fd292234166105f96fcb5acd3999c9c2abff737#diff-9ed614eee66b9e685d73446b775dc043R287

//do this in a separate thread because any wait is interrupted in this
main thread
new Thread(this::checkIfIamStillLeader, "OverseerExitThread").start();
{quote}
Can't we clean interrupt flag with {{Thread.interrupted()}} and avoid spawning
new thread ?

> SOLR-5476 depends on Overseer restart.The current strategy is to remove the
> zk node for leader election and wait for STATUS_UPDATE_DELAY +100 ms and
> start the new overseer.
> Though overseer ops are short running, it is not a 100% foolproof strategy
> because if an operation takes longer than the wait period there can be race
> condition.
