+When Bash is interactive, it ignores 'SIGTERM' (so that 'kill 0' does not kill
+an interactive shell), and 'SIGINT' is caught and handled.  When Bash receives a
+'SIGINT', it breaks out of any executing loops.  In all cases, Bash ignores
+'SIGQUIT'.  Bash ignores 'SIGTTIN', 'SIGTTOU', and 'SIGTSTP'.

+TODO: investigate this further, this seems very complicated
