Details 
Steps to reproduce:
1. Load testcase.
2. Reload.

Result: It takes a second before a new random number is displayed.
Expected: A new random number should be displayed immediately.

Workaround: use setTimeout.

More serious version: if you do the same thing in an inline script, the content
never paints (bug 155312).

Is this still an issue?
Depends on: 144587

    
    

    
  
Yes.  If I set nglayout.initialpaint.delay to 2000 in 04/24:08 on WinXP, I still
see this bug.  If I leave it at the default (250ms?), this bug is hard to notice.

    
    

    
  
Saving the testcase locally and trying it - MSIE6 is about twice as fast as 
with trunk 2004050907 on win-xp
