* (and that therefore the number of cycles to delay has already passed).
* As DELAY_CYCLES (through DELAY_NS / DELAY_US) is used by software SPI bit banging to drive
* LCDs and therefore might be called very, very often, this seemingly improbable situation did
* actually happen in reality. It resulted in apparently random print pauses of ~17.9 seconds
