* SIGILL has not been tested.
* SIGFPE doesn't seem to work?
* SIGSEGV does not catch writing to a NULL pointer (that shuts down
* your app; can you say "segmentation violation core dump"?).
* SIGTERM comes from what kind of termination request exactly?
* SIGBREAK is indeed produced by pressing Ctrl-Break.
* SIGABRT is produced by calling abort.
