 Just look at rubysig.h

#define DEFER_INTS {rb_prohibit_interrupt++;}
#define ALLOW_INTS {rb_prohibit_interrupt--; CHECK_INTS;}

# define CHECK_INTS if (!rb_prohibit_interrupt) {\
    if (rb_trap_pending) rb_trap_exec();\
    if (rb_thread_pending && !rb_thread_critical) rb_thread_schedule();\
}

 ruby will not check the interrupts for this block, nor will try to
 re-schedule the thread.
