You'll never catch SIGKILL or SIGSTOP.

"Graceful shutdown" after SIGSEGV, SIGFPE, SIGILL is no good, as these
are hints to program bugs, and continuing after such a signal is
dangerous and can do more harm than good, so bogofilter should die from
these signals as it does now.

SIGABRT is used for debugging exclusively, when the internal state is
corrupted, so it should not be trapped either for the reasons given
above for SIGSEGV et al.
