var asyncsLeft = 0;
for (var i=0;i<10;++i){
   asyncsLeft++;
   doSomethingAsyncWithCallback(function(){
     // This should be called when each asynchronous item is complete
     asyncLeft--;
     if (asyncsLeft==0){
       // This is the last one!
     }
   });
}

for (var i=0;i<result.qry.ROWCOUNT;i++) {
  myAsync(i, myCallback);
}

function myCallback(i){
  //set result.qry.ROWCOUNT to a var somewhere above if it's not available in this scope
  if(i == (result.qry.ROWCOUNT - 1)){
     //now you know you're actually done with all requests
  }
}
function myAsync(i,callback){
  ///do work
  callback(i);
}
