[Asterisk-Dev] busy-wait loops in pbx_dundi

[Luigi Rizzo]

while applying the timeval changes, i noticed that pbx_dundi.c
is full of busy-wait loops of the form

	while (!some_condition) {
		usleep(1);
	}

could someone comment how one avoids that this code eats 100% of the
CPU and how high the risk is ?

	thanks
