<p>
High performant source reloader
</p>
<p>
This class acts as <a href="../Rack.html">Rack</a> middleware.
</p>
<p>
What makes it especially suited for use in a production environment is that
any file will only be checked once and there will only be made one system
<a href="Reloader.html#M000285">call</a> stat(2).
</p>
<p>
Please note that this will not reload files in the background, it does so
only when actively called.
</p>
<p>
It is performing a check/reload cycle at the start of every request, but
also respects a cool down time, during which nothing will be done.
