I have a function `constGrid(arg1)` to be called 3 times to build extjs grid when form loads. My page has other fields also. what is really want is how should i call the constGrid method so that my page does not wait for them to load and does not hang till the method completion.

`onLoad(function() {
 for (var i=0; i<arg.length;i++) {
 constGrid(arg[i]);
 }
 ....
})`

But when i use setTimeout like below the webpage especially IE hangs till completion.

`onLoad(function() {
 for (var i=0; i <argArr.length;i++) {
 (function(i) {
 setTimeout(constGrid(argArr[i]));
 })(i));
 }
 .... 
})`

Your help in making this asynchronous will be of great help. Thanks.
