I just checked and this is just like onmouseup and onclick, there is no 
redraw between those events in Firefox and IE.

F.e. if you make the body background black in onmouseup, then start a 
calculation in onclick that takes a while, and at the end set the 
background back to white, you'll never see a black background.

(Opera doesn't seem to have the concept of single threaded javascript at 
all)
