If you're encountering enough lock-ups to cause you to need to be able to end a single tab's process regularly (which is pretty hard to do in Chrome with all the tabs having the same process name mind you) then have fun with your threaded tabs.
See, the beauty of multi-process (or multi-threaded, even) is when one tab locks up, the rest of the browser doesn't. Open Chrome's process manager (Shift+Esc) and kill the tab. And I don't know anyone that goes around trying to open tabs that will lock up the browser. That's done on accident, and it's nice to be able to do something about it when that occurs.
Coding is easy; All you do is sit staring at a terminal until the drops of blood form on your forehead.
