Hello,

is it maybe safe to call clearInterval(0)
(same way as calling free(NULL) in C language)
or should I better not rely on this?

Here is my web chat function and I wonder
if I could get rid of the very first line in it:

var intervalID:Number = 0;
var resp_lv:LoadVars = new LoadVars();
var req_lv:LoadVars = new LoadVars();

function fetch(event_num:Number, args:String):Void {
if (0 != intervalID) /* XXX remove this check? */
clearInterval(intervalID);

req_lv.event = event_num;

if (args != undefined)
req_lv.args = args;
else
delete req_lv.args;

req_lv.sendAndLoad(MODULE_URL, resp_lv, 'GET');

intervalID = setInterval(fetch, 10 * 1000, ALIVE);
}

Regards
Alex
