Some explanation might be in order ...
If you want to jump out of a signal handler, you probably want to use
sigsetjmp/siglongjmp, as they save and restore the signal mask.
If you just use setjmp/longjmp the signal will remain blocked (a
signal is blocked while its handler is executing, unless you specified
the SA_NOMASK flag to sigaction()).
Otherwise you would need to use sigprocmask() to explicitly unblock
the signal.
