      <p>A future release of Gemini Blueprint may offer the following
      additional guarantee with respect to application context creation and
      start levels:</p>

      <p>Application context creation happens asynchronously. However, the
      extender bundle does guarantee that the creation of all application
      contexts for bundles at start level <code class="literal">n</code> will be
      complete before the creation of any application context at start level
      <code class="literal">m</code>, where <code class="literal">m &gt; n</code>. Care must
      therefore be taken not to introduce any mandatory dependencies on
      services exported by bundles with higher start levels or a deadlock will
      be introduced.</p>

      <p>In a similar vein, when shutting down the extender bundle,
      application contexts at start level <code class="literal">m</code> will be shut
      down before application contexts at start level <code class="literal">n</code>,
      where <code class="literal">m &gt; n</code>.</p>
