create subclass of SingleInstanceLockFactory which warns
loadly in the event of concurrent lock attempts

                 Key: SOLR-300
                 URL: https:
//issues.apache.org/jira/browse/SOLR-300
             Project: Solr
          Issue Type: Improvement
            Reporter: Hoss Man


as noted by yonik in SOLR-240...


How about SingleInstanceLockFactory to aid in catching
concurrency bugs?
  ...
or even better, a subclass or other implementation:
SingleInstanceWarnLockFactory or
SingleInstanceCoordinatedLockFactory that log a failure if
obtain() is called for a lock that is already locked.


we should create a new subclass like Yonik describes and
change SolrIndexWriter to use this subclass if/when
"single" is specified as the lockType.
