<p>The pending processor holds shared_ptr references to the node caches. That prevents the caches from    being freed when mid::stop() is called. This change makes  sure the pending processor goes out of scope before indexing starts.</p>
<p><a href="https://github.com/styxman" class="user-mention">@StyXman</a> This resolves the problem with not freeing cache memory. Turned out to be a completely different issue. So no further changes for the stop() function needed.</p>
