Animation best power efficiency?

I have a text cursor that's modeled as a CALayer. It "blinks" with an opacity animation.

I'm in process of moving most of my animations away from CAAnimation, and instead I am driving changes myself with a CVDisplayLink. Most of my animations are temporary, things like scroll the window, etc. And when I'm done I pause the CVDisplayLink.

My question: Is it reasonable to also drive the text cursor "blink" animation by my CVDisplayLink? That would mean my CVDisplayLink never gets to pause ... but it also means maybe the render server process does get to pause?
