[Gimp-developer] Suspending display update

[Ofnuts <ofnuts laposte net>]

I have a python plugin that does very many bucket-fills (potentially 
several thousands) on small selections. While it runs I see the 
selections in the image window (but curiously, not the painting), and 
the painting on the layer thumbnail in the layers list. I assume theses 
display update take a significant amount of CPU and the script could run 
faster without them? Is there some way to suspend these updates or is 
the only technique to duplicate everything in a display-less image and 
copy back the result?
