Getting back to this question -- what happens if the -corefreq parameter in
simconfig doesn't match PTLSIM_FREQ and core_freq_hz? core_freq_hz is
primarily used by the scheduler, right? If there's a mismatch between the
parameters, does that mean that the length of a time slice is going to be
messed up?
