Other than in some embedded systems where the CPU is running one and

time is, as far as I can tell, *never* a good idea.

The only system where a busy loop can be acceptable would be a
mains-powered embedded device running a single-threaded program.
I think those devices are becoming vanishingly rare.

For battery-powered embedded devices, a busy loop is an extremely bad
idea, because it will significantly reduce the time before the
batteries have to be replaced/recharged.
