[jQuery] Why do a recursion while window unload?

[Sutra Zhou]

Another question, in jquery.js(include version 1.2.3, 1.2.6 etc.) why  
add this code:
    1. // Prevent memory leaks in IE
    2. // And prevent errors on refresh with events like mouseover in  
other browsers
    3. // Window isn't included so as not to unbind existing unload  
events
    4. jQuery(window).bind("unload", function() {
    5.     jQuery("*").add(document).unbind();
    6. });

This makes closing/refresh/navigate window more slow, especially the  
page is large(has many html elements).

Why not "have a definite object in view"? Do necessary unbind operation.

To say the least, wrap this code block with:

if (ie) {
    1. // Prevent memory leaks in IE
    2. // And prevent errors on refresh with events like mouseover in  
other browsers
    3. // Window isn't included so as not to unbind existing unload  
events
    4. jQuery(window).bind("unload", function() {
    5.     jQuery("*").add(document).unbind();
    6. });
}
