Global handlers would be ignored when using component targeting.</p>
<p>This patch considers them. To do this, we have added an extra property
to managers.</p>
<p>You can use traverse_children_handlers to increase performance when you have
a huge number of components. Put the components that are only meant to be
used with component targeting  under a single component. The hierarchy
looks like this:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="n">Root</span> <span class="o">-&gt;</span> <span class="n">Umbrella</span> <span class="n">Component</span> <span class="o">-&gt;</span> <span class="n">Component</span> <span class="mi">1</span><span class="p">,</span> <span class="n">Component</span> <span class="mi">2</span><span class="p">,</span> <span class="n">Component</span> <span class="mi">3</span><span class="p">,</span> <span class="o">...</span>
     <span class="o">-&gt;</span> <span class="n">Debugger</span><span class="p">()</span>
     <span class="o">-&gt;</span> <span class="n">etc</span>
</pre></div>

is increased). Reducing production rate will be in next commit.</p>
</li>
<li><p class="first">Small fix for new event queue handling.</p>
</li>
<li><p class="first">Fixed problem with handler cache update and concurrent event
handling/structure changes. This happens e.g. in unit tests when the
app is started and the test program adds or removes components concurrently.</p>
</li>
<li><p class="first">Optimized/clarified GenerateEvents implementation.</p>
</li>
<li><p class="first">One more concurrency problem fixed.</p>
</li>
<li><p class="first">Fixed generate events handler.</p>
</li>
<li><p class="first">Fixed bug with handler cache being always invalidated.
Avoid <tt class="docutils literal"><span class="pre">stop()</span></tt> acting as concurrent thread on <tt class="docutils literal"><span class="pre">_dispatcher()</span></tt></p>

<li><p class="first">Fixed payload length calculation in web sockets protocol.</p>
