Not making use of any dirty hacks or programming tricks at all, you can
easily convince yourself that neither of the two screens freezes: With both
displays connected and active, call SPRDEF from 80 column mode to put some
pixels in sprite number 1. 
Leave the editor (SHIFT+RETURN, RETURN), then make your sprite visible,
e.g. by entering "SPRITE 1,1,2,0,0,0,0". Now try "MOVSPR
1,115#7" and enjoy two displays at once, both non-frozen.
