Why is windows.onload executed several times?

I am binding a window.onload event like this

// It a little more complex than this, I analyze if there is any other function 
// attached but for the sake of the question it ok, this behaves the same.
window.onload = myfunction;

Onload runs twice on my local computer several times on the production server

If I changed it to jQuery equivalent

$jQuery(window).load(myfunction);

It behaves as expected (performed only once).

Could you help me understand the possible reasons why the first option does not work as intended?

Thank!
