The default is 'please die, if you would be so kind', which should
be enough, really.
An application which ignores that has a bug. After all, there is
no reason why the app should think it's not a sincere request.
The most popular signals and their numbers sent by users are
terminate (15) -- the default
interrupt (2) -- most commonly generated by hitting ctrl-C
kill (9) -- die now!
stop (17) -- most commonly generated by hitting ctrl-Z
really means pause
continue (19) -- sent by the fg command to a stopped (paused)
process
of these, only 9 and 17 cannot be ignored by the process.
