- * Note the timeout is used for the first signal, then the signal is send
- * repeatedly in interval ~1% of the original timeout to avoid race in signal
- * handling -- for example you want to use timer to define timeout for a
- * syscall:
- *
- *	 setup_timer()
- *	 syscall()
- *	 cancel_timer()
- *
- * if the timeout is too short than it's possible that the signal is delivered
- * before application enter the syscall function. For this reason timer send
- * the signal repeatedly.
- *
- * The applications need to ensure that they can tolerate multiple signal
- * deliveries.
