What most people don't realize is that cursor animation can slow down a 
program
by 20 to 90% (if it is totally without disk I/O).

Time the routine with and without cursor animation and see when the 
performance
starts to noticibly degrade. You may need to modify just how often your beach
ball spins per widget processed.
