 I think I might be able to change the code in x_flash() to do what
FSF
 Emacs does, but I am loathe to do so unless other people on
 xemacs.beta convince me that it looks better than the whole screen
 flashing. 
I, for one, would prefer it if Lars can work on Gnus in XEmacs without 
undo pain and agony.
I don't like the visual bell because it is too startling.  The FSF
Emacs change sounds like a step in the right direction to me.
