Before you continue digging this hole you should consider web browsers don't load all old tabs on startup. I have definitely had 2000+ tabs open and that didn't even slow down the browser as usually less than 100 or so are loaded at a time. I basically use tabs as bookmarks. Note that I use Firefox and not Chrome, and my tab usage is one of the reasons.
