I was going to ask about RDTSC, because BeOS needs it to boot. My question
is "Can another thread be used to simulate the RDTSC instruction?"
Apparently this is a 64 bit counter that increments until it reaches it's
max value and then starts at zero again. So what is we put a thread in the
emulator that just incremented a fake RDTSC counter, and then read the
counter whenever RDTSC is called? Will that work, or will the timing be too
far off?
