As I understand it, the debug-on-quit support is intended to catch the 
user typing C-g, as opposed to altering code that calls 'signal' so that 
it returns. If so, how about keeping the current approach for C-g, and 
merely changing 'signal' itself so that it does not return? I wrote a 
new patch to do that, and will send it to Bug#24047.
