count++;
for (var i = 0; i < 20; i++) {
html.push('<tr>');
for (var j = 0; j < 6; j++)
html.push('<td>Test: ' + count + 'cell_' + i + '_' + j + '</td>');
html.push('</tr>');
}
html.push('</table></div>');
return html.join('');

function intervalRender() {

if (!id) {
id = setInterval(function () {
jQuery('#mytable').replaceWith(getHtml());
}, 1000);
}

test case doesn't leak any memory for me.
Can you confirm this testcase doesn't leak memory for you. Else report back with exact IE version and we might reopen the ticket.
