GTKSpinner being a resource hog has definitely been a kind of general 
problem in the past. I have a bug open for a case where it was eating 
70% of CPU time on a *bare metal* nouveau system:

I'll have to check that again with the latest bits. Evolution devs 
have obviously had issues with it before too, because when I reported 
that case to them (the spinner that was actually eating my CPU time 
was in Evo), they ripped GTKSpinner out and re-introduced their own 
custom spinner:

just other data on the general topic of 'a little UI element seems to 
take more resources than you'd think it would'.
