Transmeta Crusoe is said to have a 1000 us interrupt latency whereas
a 600 MHz Intel Celeron processor has a 80 us interrupts latency,
both running BeIA/BeOS. This is probably related to code morphing.
Maybe more recent Crusoes aren't affected.
I would think that Crusoes would inheiritly have greater latency than
traditional x86 CPUs. After all, important parts of the CPU are done in
software. It's almost like using an emulator.
