So I suppose I want to restate my original offer. If anyone has a patch that you'd like tested (briefly or rigorously) in preparation for 4.7 release, please email me at info@urbits.com.

I'm again available for a couple of hours of testing, email me at info@urbits.com. Dopry, I didn't end up doing either of yours because they've since been marked ready to commit. .s
