we've discussed this before, actually:

http://mail.gnome.org/archives/gtk-perl-list/2004-April/msg00021.html

that example sets up a short number of flashes.  if you want it to 
flash slowly until the user acknowledges somehow, set the timeout to a 
slower value (half a second, one second, etc), and store the timeout 
tag so you can remove the timeout externally when you know the user has 
responded.

yes, nine times out of ten threads are more trouble than they are 
worth, and cause more problems than they solve.  for this type of 
problem, the appropriate solution is to use the event loop and 
timeouts.
