The process of putting all my open tabs into bookmarks so they can be reopened is going to be a dwarfy good time, though... XP
Speaking as somebody who maintains ~100 tabs across three windows, it's not as hard as you think. Bookmark All Tabs is really helpful; it automatically makes a folder with bookmarks of all tabs in a window.
One BAT per window, import all the bookmarks, make your windows, Open All in Tabs on each folder... done!
