<p>Invoke a default callback for <em class="parameter"><code>callback_name</code></em>
, with in arguments
specified by <em class="parameter"><code>in</code></em>
and <em class="parameter"><code>in_size</code></em>

<p>This function should only be called by gnome-vfs modules.</p>
<p>If this function is called from an async job thread, it will invoke
the current async handler for <em class="parameter"><code>callback_name</code></em>

handler is set, or the function is not called from an async job
thread, the regular handler, if any, will be invoked instead. If no
handler at all is found for <em class="parameter"><code>callback_name</code></em>
