Review comment:
Hey good point; needToReloadLuceneSPI should be volatile and
reloadLuceneSPI() should be synchronized. In practice it'd only happen if
someone had some strange Solr hacks / plugins because the only callers of the
couple methods that touch this boolean do so once and then never touch it
again. But still, lets be thorough.
