If no sockets or actors are used in zloop, zsys_init() does not get run and zsys interrupt handler does not get initialized. This means that interrupts will not work correctly in zloop if, for example, only timers are used. zsys_init() is safe to call multiple times, so we ensure that it's called when new zloop instance is created.
