Вот моя функция:

var showMessage = (function() {
	var i = 0;
	var messCount = 0;
	var maxMessCount = 3;//Количество возможных отображаемых сообщения одновременно
	return function(type, msg, delay) {
		if(messCount >= maxMessCount) {
			var remElem = $('#showMess_'+(i-maxMessCount));
			remElem.slideUp(300, function() {
				alert('a');
				//console.log('End anim, remove: ' + remElem.attr('id'));
				//remElem.remove();
				//messCount = messCount > 0 ? messCount - 1 : 0;
			});
			remElem.remove();
			messCount = messCount > 0 ? messCount - 1 : 0;
		}

		$('.messageDiv').append('<div class="'+type.match(/\w+$/)+'" id="showMess_'+i+'" style="display: none;">'+msg+'</div>');
		messCount++;

		$('#showMess_'+i).slideDown(300, function(){
			$(this).delay(delay).slideUp(300, function(){
				if($(this).length) {
					$(this).remove();
					messCount = messCount > 0 ? messCount - 1 : 0;
				}
			});
		});
		i++;
		return false;
	}
})();
