reset signal handlers before running scripts/hooks
Front-ends or libraries may set signals to be ignored, which gets inherited across fork and exec. This can cause scripts to malfunction if they expect the signal. To make matters worse, scripts written in bash can't reset signals that were ignored when bash was started.
