> I'm having trouble when I start up the schemaless example after shutting down.
> I first tracked this down to the fact that the run example tool is getting an
> error when it tries to create the SolrCore (again, it already exists) and so
> it deletes the cores instance dir which leads to tlog and index lock errors
> in Solr.
> The reason it seems to be trying to create the core when it already exists is
> that the run example tool uses a core status call to check existence and
> because the core is loading, we don't consider it as existing. I added a
> check to look for core.properties.
> That seemed to let me start up, but my first requests failed because the core
> was still loading. It appears CoreContainer#getCore is supposed to be
> blocking so you don't have this problem, but there must be an issue, because
> it is not blocking.
