How can I show a list of every thread running spawned by setTimeout/setInterval

Question

I want to do this either by pure javascript or any sort of console in a browser or whatever.

Is it possible?

Thanks

Further explanations: I want to debug

Finally done, it was interesting for me so I spent some time trying to come up with something, and here it's

It overrides browser's setTimeout and fill active status of current active calls in window._activeSetTimeouts hash, with window._showCurrentSetTimeouts() demo function that displays current setTimeout calls that are waiting.

if(typeof window._setTimeout =='undefined') {
window._setTimeout=window.setTimeout;

window._activeSetTimeouts={};
window._activeSetTimeoutsTotal=0;
window._setTimeoutCounter=0;
window._showCurrentSetTimeouts=function() {
    var tgt=document.getElementById('_settimtouts');
    if(!tgt) {
    tgt=document.createElement('UL');
    tgt.style.position='absolute';
    tgt.style.border='1px solid #999';
    tgt.style.background='#EEE';
    tgt.style.width='90%';
    tgt.style.height='500px';
    tgt.style.overflow='auto';
    tgt.id='_settimtouts';

    document.body.appendChild(tgt);
    }

    tgt.innerHTML='';
    var counter=0;
    for(var i in window._activeSetTimeouts) {
        var li=document.createElement('LI');
        li.innerHTML='[{status}] {delay} ({calltime})
{cb}
'.f(window._activeSetTimeouts[i]);
        li.style.background=(counter++%2)?'#CCC' : '#EEB';
        tgt.appendChild(li);
    }
}
window.setTimeout=function(cb, delay) {
    var id = window._setTimeoutCounter++;
    var handleId = window._setTimeout(function() {
    window._activeSetTimeouts[id].status='exec';
    cb();
    delete window._activeSetTimeouts[id];
    window._activeSetTimeoutsTotal--;
    }, delay);

    window._activeSetTimeouts[id]={
    calltime:new Date(),
    delay:delay,
    cb:cb,
    status:'wait'
    };
    window._activeSetTimeoutsTotal++;
    return id;
}

//the following function is for easy formatting

String.prototype.f=function(obj) {
var newStr=this+'';
if(arguments.length==1) {
if(typeof(obj)=='string') {
    obj={x:obj};
}


for(var i in obj) {
    newStr=newStr.replace(new RegExp('{'+i+'}', 'g'), obj[i]+'');
}
newStr+='';

} else {
    for(var i=0; i
