This would not fulfil the requirement that at most three service calls must be done. For doing this, you also have to monitor the time (though you don't have to do it using a timer).

It does fulfill the requirements. It does monitor the time.

I'm running on a system where Time::HiRes is not availabl

For this particular example, install it or use select. In general, this would be the aforementioned "no API available" reason.

I find that doing one service call in average takes 0.3 seconds or longer, so I don't consider it worth saving cycles by doing micro-sleeps

The reason it's ok to waste CPU is that it's not worth saving CPU cycles? That's not a reason for using a busy loop; it's not even a valid argument.

I'm running on a system where there isn't going on much more critical stuff except my process, so I don't care eating CPU cycles by a busy loop

So the reason for using a busy loop is that you're no worst off at the best of times? I'm not sold.
