Never kill terminals, for example not even on errors or quit or colab restart.

Right now when you disconnect from sleep, terminals still work. Users may not be connected to floobits, but the terminal still works. When we restart colab that kills terminals, when bad things happen we kill terminals. How about we just never do that because that could be really bad for users if they're in the middle of something important. Why can't it just disconnect but keep the terminal working.
