TOPS-20 (Twenex) loses your terminal type on a detach/attach.
With UNIX, it would probably be possible to have a .attach or
a .continue file (analogous to the .login/.cshrc/.logout) to handle
the change of terminal.  Of course, stopped jobs would lose, but
oh well.

On the TOPS-10 system at Worcester Polytechnic Inst. before they
got a 20, a feature called "freeze" was installed.  With it, one
could suspend a process into a file and continue at any later
date.  The restart was invisible--except for the tty, all open
files were reopened to the right place.  Anyone start on such a
beast?
