Synchronize supposedly is blocked when there is too much GUI  thread 
activity and the appropriate event does not get handled. Maybe when 
dragging a window GTK blocks in some event, which is 100% GUI  thread 
activity from the application's point of view.

IMHO, This kind of polling is not a good idea (but just a work around). 
But of course you can't change what the GTK does when dragging a window :(.
