(Chris, Rachel pointed me your way, but please let me know if I should reroute!)

My Macbook is in an unhappy state right now, which means I have gotten a bunch of opportunities to use tab restoration -- a feature I'm very grateful for.

The issue I've observed is that if your machine crashes before you've had the chance to press "Restore," those tabs are lost. (i.e. it doesn't offer to "Restore" the next time you open Chrome, even if you didn't do anything in Chrome / decline to restore.)

I realize it's unlikely for this to happen in everyday use, but it's pretty easy to do if the machine is boot-looping :)
