The package 'screen' allows a similar thing.  It manages virtual
shells on a terminal and allows you to detach the whole lot in one
go, and then reattach from anywhere.  I used to use it at University
when terminals were hard to hold on to all day (due to student demand).
Useful for that FTP that's going to take all day. :)
