<p>Earlier, one process handled nat_traversal timeouts, so static<br>
iteration counter correctly distributed keepalives across timeout<br>
interval.</p>

<p>Now timeouts are sent to various processes, each of which had its own<br>
counter, resulting in erratic keepalive delivery.</p>

<p>Fix moves the iteration counter into shared memory.</p>

<p>LMK if there is a more preferred way to contribute changes.</p>
