[Seeking advice] Flickering

[sixtyfive]

Hi, thanks for a great gem, which I've begun using for every script that'll run a while. There's one small nitpick that I can't figure out: is there a way to get rid of the flickering seen here in the video? I'm assuming I'm doing something wrong or else someone would have already noticed it before me?

All I'm doing here is to call Whirly.start once, then entries.each_with_index{|e,i| Whirly.status="... #{i}/#{entries.size}" if i%50==0; ...} and then Whirly.stop.
