This is one of the unresolved problems mentioned in <http://twistedmatrix.com/trac/ticket/2991>. The comment I left on that ticket regarding this was:
Clearing the screen is a side-effect of resetting the terminal.
Resetting the terminal is a shortcut for figuring out what the
current terminate state is (for example, the position of the cursor,
the current character attributes, etc). All of those things could
be dealt with separately to avoid also clearing the screen.
So this can be fixed, it's just a matter of programming. :)
