You can mask the INTR and STOP signals with:
screen.tty_signal_keys(intr='undefined', stop='undefined')

(or remap them to other keys)

It seems my reference documentation isn't showing the methods inherited 
from subclasses anymore.  I'll have to look into fixing that.  The 
method is defined in the RealTerminal class.
