they just will not reach the process.
oops..
no oops, that's all right.
- when creating Signal instance, corresponding signal becames
blocked
```d
final class Signal : EventSource {
enum int sigInt = SIGINT;
enum int sigTerm = SIGTERM;
ulong number;
this(int signo) {
super('S');
sigset_t sset;
sigset_t old_sset;
/* block the signal */
sigemptyset(&sset);
sigaddset(&sset, signo);
sigprocmask(SIG_BLOCK, &sset, &old_sset);
id = signalfd(-1, &sset, SFD_CLOEXEC);
```
- upon receiving SIGINT stopperIdleS0() is called.
now stop variable of EventQueue is false
- next call to wait() method just return.
(remember, signals are still blocked)
