Correct me if I'm wrong, but IIRC, the original mosix was useless for
the compilation speed improvements due to the fact that a typical
compilation process doesn't last long enough to even be considered
for migration. And even if the migration would be forced, the migration
overhead compared to the process execution time, would kill all the time
savings.
