<p>This module provides a duplicate interface to the <a class="reference internal" href="_thread.html#module-_thread" title="_thread: Low-level threading API."><tt class="xref py py-mod docutils literal"><span class="pre">_thread</span></tt></a> module.  It is
meant to be imported when the <a class="reference internal" href="_thread.html#module-_thread" title="_thread: Low-level threading API."><tt class="xref py py-mod docutils literal"><span class="pre">_thread</span></tt></a> module is not provided on a
platform.</p>
<p>Suggested usage is:</p>
<div class="highlight-python3"><div class="highlight"><pre><span class="k">try</span><span class="p">:</span>
    <span class="kn">import</span> <span class="nn">_thread</span>
<span class="k">except</span> <span class="ne">ImportError</span><span class="p">:</span>
    <span class="kn">import</span> <span class="nn">dummy_thread</span> <span class="k">as</span> <span class="nn">_thread</span>
</pre></div>
</div>
<p>Be careful to not use this module where deadlock might occur from a thread being
created that blocks waiting for another thread to be created.  This often occurs
with blocking I/O.</p>
