When trapping the INT signal in order to return from the #response me…

…thod,

it is possible to get into a state where it is still trapping even when the
method has returned, which results in a LocalJumpError.

I'm not convinced that trapping to return is the best thing to do but if
you do trap to return, you should restore the original trap when the method
exits.
