  runUntil
  	"Step until an expression evaluates to other than false, reporting an erroer if it doesn't evaluate to true.
  	 Remember the expression in an inst var.  If shift is pressed when the expression is supplied, don't update the UI.
  	 If shift is pressed while stepping, stop stepping.  Using a user interrupt to break out would be more natural
  	 but Squeak currently doesn't provide a UserInterrupt expection.  It should do."
