The following small change appears to restore the old behavior for SIGINT.
The question is whether this should be applied to other signals that are
known to cause process termination, such as SIGQUIT.

I'm also not sure whether it's really necessary to test sigtrapped[], or
whether I've got the sense of that test right.
