Constructor. Creates the internal signal event, handling the specified
signals. The event (accessible via the event() method) must be
registered with epoll.
The list of signals handled may be extended after construction by
calling the register() method.
Note that the signals will be handled with a delay of up to single
epoll cycle. This is because the signal extension is synced with the
EpollSelectDispatcher. This makes it unsuitable to handle critical
signals (like SIGABRT or SIGSEGV) where the application shouldn't
be allowed to proceed in the general case; for these cases setup an
asynchronous signal handler using sigaction instead.
