<p>Initialization. read_freq, treshold and timeout parameters are used
when looping.</p>
<dl class="fields">
<dt>Parameters:</dt>
<dd><ul class="nomargin-top">
<li><strong class="pname"><code>watch_manager</code></strong> (WatchManager instance) - Watch Manager.</li>
<li><strong class="pname"><code>default_proc_fun</code></strong> (instance of ProcessEvent) - Default processing method.</li>
<li><strong class="pname"><code>read_freq</code></strong> (int) - if read_freq == 0, events are read asap, if read_freq is > 0,
this thread sleeps max(0, read_freq - timeout) seconds. But if
timeout is None it can be different because poll is blocking
waiting for something to read.</li>
<li><strong class="pname"><code>treshold</code></strong> (int) - File descriptor will be read only if its size to read is >=
treshold. If != 0, you likely want to use it in combination with
read_freq because without that you keep looping without really
reading anything and that until the amount to read is >=
treshold. At least with read_freq you may sleep.</li>
<li><strong class="pname"><code>timeout</code></strong> (int) - see http://docs.python.org/lib/poll-objects.html#poll-objects</li>
