I am well aware of this "solution".
I said "reasonably implement". Your suggestion, as I truly hope you know, pegs CPU usage at 100% and consumes all available processing power. This is not reasonable, except in very specific use cases.

Also, if you try this on the cRIO under Java, you'll notice that it hangs every single thread other than the main thread for the duration, because Squawk does cooperative multitasking and this code has no "Thread.yield()". (It's still a bad idea in C++, of course, but not quite as horrendous.)
