It works on Amiga now, too. It can still use some optimizations in

BogoMIPS rating dropped by ca 2.5% and is now under 16, for a 25 MHz
68040.

Seems like everything (Atari/ARAnyM and Amiga) still works when using
handle_simple_irq instead of handle_level_irq. As a bonus, BogoMIPS is
above 16 again.

Your bogomips benchmark would be the best-case penalty, right?

Have you tried say, sending a ping flood to measure throughput and
latency?

No, I haven't compared network performance.

when I'm talking to journalists I just say "programmer" or something like that.
