Or you can add method close to call it in all way.</p></pre>

1) m_env != null means valid atm, therefore I can call here close
2) after this, the destructor is over, no need to null it, if you access the database object after/during destruction, all is lost.</p></pre>

Unfortunately, the Baloo::Database itself not, as open() might race against other open calls (we have one unique db object in baloo).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">=> add non-recursive mutex (recursive mutex not needed, one just must avoid to call isOpen() or path() inside open, that is done, else no unit test works).</p></pre>
